Implement multi-memory for classic-interpreter. Support core spec (and bulk memory) opcodes now,
and will support atomic opcodes, and add multi-memory export APIs in the future.
PS: Multi-memory spec test patched a lot for linking test to adapt for multi-module implementation.
The table index in the call_indirect/return_call_indirect opcode should be
one byte 0x00 when ref-types/GC isn't enabled, and should be treated as
leb u32 when ref-types/GC is enabled.
And make aot compiler bail out if ref-types/GC is disabled by command line
argument while ref-types instructions are used.
Any use of a table index that isn't exactly a null byte (`0x00`) means that
the module makes use of the reference types proposal. This is important
to track because `aot_compiler.c` will blindly assume that all table indices
are a single byte long otherwise.
This fixes a crash in WAMR for modules that contain multi-byte encodings
of table indices in `call_indirect` but make no other use of reference types
features.
There's probably a number of other places where the bh_leb_read could be used (e.g. aot loader)
but I'm making the change as small as possible. Further refactoring can be done later.

Fix several issues of GC and exception handling in wasm loader:
- Should restore param_reftype_maps/param_reftype_map_count/param_count
in the handling of opcode throw
- Should set wasm_ref_type when pushing param types of tag type and block type
if the type is a multi-byte type
- Should set init_values.data as NULL for opcode struct.new_default in load_init_expr
This PR fixes the issues reported in #3411.

Check whether the indices overflow UINT32_MAX or not for:
- import function count + function count
- import global count + global count
- import tag count + tag count
This PR fixes the issue reported by Oss-fuzz test (#69920).
The wasm loader is failing when multi-module support is on and the dependent
modules are not found; this enforces the AOT compiler integrations to prepare
dependent modules while it isn't necessary.
This PR allows allows missing imports in wasm loader and report error in wasm
instantiation instead, which enables the integrated AOT compiler to work as if
the multi-module support isn't turned on.

In wasm_loader_pop_frame_offset, when the stack is in polymorphic state
and the stack top operand is VALUE_TYPE_ANY, if we popping I64/F64
operand, we should pop one offset but not two offsets.
The issue was reported in #3513 and #3514.
- possible integer overflow in adjust_table_max_size:
unsigned integer overflow: 2684354559 * 2 cannot be represented in type 'uint32'
- limit max memory size in wasm_runtime_malloc
- add more checks in aot loader
- adjust compilation options
Support to get `wasm_memory_type_t memory_type` from API
`wasm_runtime_get_import_type` and `wasm_runtime_get_export_type`,
and then get shared flag, initial page cout, maximum page count
from the memory_type:
```C
bool
wasm_memory_type_get_shared(const wasm_memory_type_t memory_type);
uint32_t
wasm_memory_type_get_init_page_count(const wasm_memory_type_t memory_type);
uint32_t
wasm_memory_type_get_max_page_count(const wasm_memory_type_t memory_type);
```
When datacount section exists, loader will check whether the data count
read from data segment section is same with the data count read from
datacount section, but the value of latter can be 0, loader should not
skip the check when the latter is 0. This fixes#3491.
And fix handle_name_section return value not checked issue and early
return true issue after handle_name_section.
And also add the failed case in #3491 to ba-issues.
Fix several issues in wasm loader:
- Parse a block's type index with leb int32 instead leb uint32
- Correct dst dynamic offset of loop block arguments for opcode br
when copying the stack operands to the arguments of loop block
- Free each frame_csp's param_frame_offsets when destroy loader ctx
- Fix compilation error in wasm_mini_loader.c
- Add test cases of failed issues
This PR fixes issue #3467 and #3468.
- Add a marco to limit the maxi allocable memory size of fuzz test to
2GB to avoid libFuzzer out-of-memory
- Check global type in load_global_import and load_global_section
- Update spec test cases to commit bc76fd79cfe61033d7f4ad4a7e8fc4f996dc5ba8 on Apr. 3
- Update wabt binary to 1.0.34 to support newer spec cases
- Add comparison between table declared elem type and table elem segment value type
- Add a function to decide whether to execute test cases in a running mode
- Keep using interpreter in GC spec because wat2wasm in wabt can't compile if.wast w/o errors
- Re-factoring threads spec test case processing
- Since wabt 1.0.34 release isn't compatible with ubuntu 20.04, compile it from source code
- Disable CI to run aot multi-module temporarily, and will enable it in another PR
Add flag `LoadArgs.clone_wasm_binary` to control whether to clone the wasm/aot
binary in wasm-c-api module. If false, API `wasm_module_new_ex` won't clone the
binary, which may reduce the footprint.
Add flag `LoadArgs.wasm_binary_freeable` to control whether the wasm/aot binary
may be freed after instantiation for wamr API `wasm_runtime_load_ex`, if yes, then
for some running modes, the wasm/aot module doesn't refer to the input binary
again so developer can free it after instantiation to reduce the footprint.
And add API `wasm_module_is_underlying_binary_freeable` and
`wasm_runtime_is_underlying_binary_freeable` to check whether the input binary
can be freed after instantiation for wasm-c-api and wamr api.
And add sample to illustrate it.
Support getting global type from `wasm_runtime_get_import_type` and
`wasm_runtime_get_export_type`, and add two APIs:
```C
wasm_valkind_t
wasm_global_type_get_valkind(const wasm_global_type_t global_type);
bool
wasm_global_type_get_mutable(const wasm_global_type_t global_type);
```
If there is no else branch, make a virtual else opcode for easier integrity
check and to copy the correct results to the block return address for
fast-interp mode: change if block from `if ... end` to `if ... else end`.
Reported in issue #3386, #3387, #3388.
Fix the integer overflow issue when checking target branch depth in opcode
br_table, and fix is_32bit_type not check VALUE_TYPE_ANY issue, which may
cause wasm_loader_push_frame_offset push extra unneeded offset.
Fix wasm loader integrity checks for opcode ref.func and opcode else:
for opcode ref.func, the function must be an import, exported, or present in a
table elem segment or global initializer to be used as the operand to ref.func,
for opcode else, there must not be an else opcode previously.
Reported in #3336 and #3337.
And fix mini loader PUSH_MEM_OFFSET/POP_MEM_OFFSET macro
definitions due to the introducing of memory64 feature.
Enhance the GC subtyping checks:
- Fix issues in the type equivalence check
- Enable the recursive type subtyping check
- Add a equivalence type flag in defined types of aot file, if there is an
equivalence type before, just set it true and re-use the previous type
- Normalize the defined types for interpreter and AOT
- Enable spec test case type-equivalence.wast and type-subtyping.wast,
and enable some commented cases
- Enable set WAMR_BUILD_SANITIZER from cmake variable
- Add new API wasm_runtime_load_ex() in wasm_export.h
and wasm_module_new_ex in wasm_c_api.h
- Put aot_create_perf_map() into a separated file aot_perf_map.c
- In perf.map, function names include user specified module name
- Enhance the script to help flamegraph generations
Fix the warnings and issues reported:
- in Windows platform
- by CodeQL static code analyzing
- by Coverity static code analyzing
And update CodeQL script to build exception handling and memory features.
Adding a new cmake flag (cache variable) `WAMR_BUILD_MEMORY64` to enable
the memory64 feature, it can only be enabled on the 64-bit platform/target and
can only use software boundary check. And when it is enabled, it can support both
i32 and i64 linear memory types. The main modifications are:
- wasm loader & mini-loader: loading and bytecode validating process
- wasm runtime: memory instantiating process
- classic-interpreter: wasm code executing process
- Support memory64 memory in related runtime APIs
- Modify main function type check when it's memory64 wasm file
- Modify `wasm_runtime_invoke_native` and `wasm_runtime_invoke_native_raw` to
handle registered native function pointer argument when memory64 is enabled
- memory64 classic-interpreter spec test in `test_wamr.sh` and in CI
Currently, it supports memory64 memory wasm file that uses core spec
(including bulk memory proposal) opcodes and threads opcodes.

The PR #3259 reverted PR #3192, it fixes#3210 but makes #3170 failed again.
The workaround is that we should update `ctx->dynamic_offset` only for opcode br
and should not update it for opcode br_if. This PR fixes both issue #3170 and #3210.
Should not update `ctx->dynamic_offset` in emit_br_info, since the `Part e` only
sets the dst offsets, the operand stack should not be changed, e.g., the stack
operands are to be used by the opcodes followed by `br_if` opcode.
Reported in https://github.com/bytecodealliance/wasm-micro-runtime/issues/3210.
Fix the errors reported in the sanitizer test of nightly run CI.
When the stack is in polymorphic state, the stack operands may be changed
after pop and push operations (e.g. stack is empty but pop op can succeed
in polymorphic, and the push op can push a new operand to stack), this may
impact the following checks to other target blocks of the br_table opcode.
