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.

Now that the filesystem implementation is now complete, the previous
test filters on Windows can be removed. Some of the tests only pass when
certain environment variables have been set on Windows so an extra step
has been added in the wasi test runner script to modify the test config
files before the tests begin.
Implement the GC (Garbage Collection) feature for interpreter mode,
AOT mode and LLVM-JIT mode, and support most features of the latest
spec proposal, and also enable the stringref feature.
Use `cmake -DWAMR_BUILD_GC=1/0` to enable/disable the feature,
and `wamrc --enable-gc` to generate the AOT file with GC supported.
And update the AOT file version from 2 to 3 since there are many AOT
ABI breaks, including the changes of AOT file format, the changes of
AOT module/memory instance layouts, the AOT runtime APIs for the
AOT code to invoke and so on.
This PR adds the initial support for WASM exception handling:
* Inside the classic interpreter only:
* Initial handling of Tags
* Initial handling of Exceptions based on W3C Exception Proposal
* Import and Export of Exceptions and Tags
* Add `cmake -DWAMR_BUILD_EXCE_HANDLING=1/0` option to enable/disable
the feature, and by default it is disabled
* Update the wamr-test-suites scripts to test the feature
* Additional CI/CD changes to validate the exception spec proposal cases

Update the wabt release binary name for macos and fix a syntax error:
```bash
./test_wamr.sh: line 356: syntax error near unexpected token `;'
./test_wamr.sh: line 356: ` ;&'
```
Most of the WASI filesystem tests require at least creating/deleting a
file to test filesystem functionality so some additional filesystem APIs
have been implemented on Windows so we can test what has been
implemented so far. For those WASI functions which haven't been
implemented, we skip the tests. These will be implemented in a future PR
after which we can remove the relevant filters.
Additionally, in order to run the WASI socket and thread tests, we need
to install the wasi-sdk in CI and build the test source code prior to
running the tests.
To run it locally:
```bash
export TSAN_OPTIONS=suppressions=<path_to_tsan_suppressions.txt>
./test_wamr.sh <your flags> -T tsan
```
An example for wasi-threads would look like:
```bash
export TSAN_OPTIONS=suppressions=<path_to_tsan_suppressions.txt>
./test_wamr.sh -w -s wasi_certification -t fast-interp -T tsan
```
When doing more investigations related to this PR:
https://github.com/bytecodealliance/wasm-micro-runtime/pull/2619
We found that in some scenarios the constant might not be directly
available to the LLVM IR builder, e.g.:
```
(func $const_ret (result i32)
i32.const -5
)
(func $foo
(i32.shr_u (i32.const -1) (call $const_ret))
(i32.const 31)
)
```
In that case, the right parameter to `i32.shr_u` is not constant, therefore
the `SHIFT_COUNT_MASK` isn't applied. However, when the optimization
is enabled (`--opt-level` is 2 or 3), the optimization passes resolve the
call into constant, and that constant is poisoned, causing the compiler to
resolve the whole function to an exception.
This PR adds the Cosmopolitan Libc platform enabling compatibility with multiple
x86_64 operating systems with the same binary. The platform is similar to the
Linux platform, but for now only x86_64 with interpreter modes are supported.
The only major change to the core is `posix.c/convert_errno()` was rewritten to use
a switch statement. With Cosmopolitan errno values depend on the currently
running operating system, and so they are non-constant and cannot be used in array
designators. However, the `cosmocc` compiler allows non-constant case labels in
switch statements, enabling the new version.
And updated wamr-test-suites script to add `-j <platform>` option. The spec tests
can be ran via `CC=cosmocc ./test_wamr.sh -j cosmopolitan -t classic-interp`
or `CC=cosmocc ./test_wamr.sh -j cosmopolitan -t fast-interp`.
Support muti-module for AOT mode, currently only implement the
multi-module's function import feature for AOT, the memory/table/
global import are not implemented yet.
And update wamr-test-suites scripts, multi-module sample and some
CIs accordingly.
On posix-like platforms, the rest of wasi-threads tests
should pass after the recent changes including the following PRs:
#2516, #2524, #2529, #2571, #2576 and #2582.
This improves test consistency between typical local environments and
github runners.
This is necessary for some of latest wasi-threads tests.

Add simple infrastructure to add more unit tests in the future. At the moment tests
are only executed on Linux, but can be extended to other platforms if needed.
Use https://github.com/google/googletest/ as a framework.
As a part of stress-testing we want to ensure that mutex implementation is working
correctly and protecting shared resource to be allocated from other threads when
mutex is locked.
This test covers the most common situations that happen when some program uses
mutexes like locks from various threads, locks from the same thread etc.
We need to make a test that runs longer than the tests we had before to check
some problems that might happen after running for some time (e.g. memory
corruption or something else).
Tests were failing because the right permissions were not provided to iwasm.
Also, test failures didn't trigger build failure due to typo - also fixed in this change.
In addition to that, this PR fixes a few issues with the test itself:
* the `server_init_complete` was not reset early enough causing the client to occasionally
assume the server started even though it didn't yet
* set `SO_REUSEADDR` on the server socket so the port can be reused shortly after
closing the previous socket
* defined receive-send-receive sequence from server to make sure server is alive at the
time of sending message
LLVM PGO (Profile-Guided Optimization) allows the compiler to better optimize code
for how it actually runs. This PR implements the AOT static PGO, and is tested on
Linux x86-64 and x86-32. The basic steps are:
1. Use `wamrc --enable-llvm-pgo -o <aot_file_of_pgo> <wasm_file>`
to generate an instrumented aot file.
2. Compile iwasm with `cmake -DWAMR_BUILD_STATIC_PGO=1` and run
`iwasm --gen-prof-file=<raw_profile_file> <aot_file_of_pgo>`
to generate the raw profile file.
3. Run `llvm-profdata merge -output=<profile_file> <raw_profile_file>`
to merge the raw profile file into the profile file.
4. Run `wamrc --use-prof-file=<profile_file> -o <aot_file> <wasm_file>`
to generate the optimized aot file.
5. Run the optimized aot_file: `iwasm <aot_file>`.
The test scripts are also added for each benchmark, run `test_pgo.sh` under
each benchmark's folder to test the AOT static pgo.
The spec test cases of thread proposal were updated, the `thread` keyword was added
in case `atomic_wait_notify.wast`:
```wast
(thread $T1 (shared (module $Mem))
...
)
(thread $T2 (shared (module $Mem))
...
)
```
We disable these cases since parsing keyword `thread` isn't supported in the
wamr-test-suites script runtest.py yet.
