Implement AOT static PGO (#2243) 
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.

Introduction

CoreMark's primary goals are simplicity and providing a method for testing only a processor's core features.

Source: https://github.com/eembc/coremark

Building

Please build iwasm and wamrc, refer to:

And install WASI SDK, please download the wasi-sdk release and extract the archive to default path /opt/wasi-sdk.

And then run ./build.sh to build the source code, file coremark.exe, coremark.wasm and coremark.aot will be generated.

Running

Run ./run.sh to test the benchmark, the native mode, iwasm aot mode and iwasm interpreter mode will be tested respectively.

Run ./test_pgo.sh to test the benchmark with AOT static PGO (Profile-Guided Optimization) enabled, please refer here to install tool llvm-profdata and build iwasm with cmake -DWAMR_BUILD_STATIC_PGO=1.
