* shared heap enhancement: modify memory check for aot_check_memory_overflow to accomodate shared heap chain * shared heap enhancement in AOT * use alloca for func ctx shared heap cache value * use correct alloca for func ctx shared heap cache value * enable shared heap chain aot test and bug fix * Fix a missing argument on 32bits platform, still has the shared heap chain iteration problem * Fix shared heap chain iteration problem on 32bits platform * fix AOT bulk memory bounds checks compliation issue * fix AOT bulk memory bounds checks on 64 bits platform * refactor aot memory check * refactor AOT bulk memory bounds checks * add more unit test for shared heap * finished organizing unit test for shared heap and enable x86_32 for shared heap unit test * cover a corner case for bulk memory overflow check * try func call to replace shared heap chain traverse * fix compilation error in JIT and potentially load nullptr * add option for wamrc to enable single shared heap/multi shared heap, and update shared heap unit tests and sample * cr suggestions: 1. check potiential underflow 2. refactor and use separate function for bulk memory and normal memroy 3. static assert 4. add more comments 5. remove unused code
