Changes

Avoid linking asanrtl.bc at compile time. Symbols necessary for GPU ASan functionality are provided via asanified 'libompdevice.a' installed at /opt/rocm/llvm/lib/asan.
Replace '-mlink-bitcode-file' to '-mlink-builtin-bitcode' in lit tests for asanrtl.bc just like other bitcode libs.

- Avoid linking asanrtl.bc at compile time. Symbols necessary for GPU ASan functionality are provided via asanified 'libompdevice.a' installed at `/opt/rocm/llvm/lib/asan`. - Replace '-mlink-bitcode-file' to '-mlink-builtin-bitcode' in lit tests for asanrtl.bc just like other bitcode libs.

clang/lib/Driver/ToolChains/AMDGPU.cpp

+    const AMDGPUToolChain &AMDGPU =
+        static_cast<const AMDGPUToolChain &>(getToolChain());
+    StringRef ASanPath = Args.MakeArgString(
+        AMDGPU.getRocmInstallationPath().str() + "/lib/llvm/lib/asan");


This shouldn't be hardcoding a relative path like this, what was wrong with the existing getAsanRTLPath

getAsanRTLPath returns the absolute path of asanrtl.bc bitcode library which is /opt/rocm/amdgcn/bitcode/asanrtl.bc .
The non-asan openmp libompdevice.a is installed in /opt/rocm/llvm/lib/amdgcn-amd-amdhsa and asan one in /opt/rocm/llvm/lib/asan by default.

I will check again how to avoid hardcoding this for asan. It dosen't happen for non-asan libompdevice.a.

All the bitcode libraries should come from the same exact place. We should not support mixing and matching different source directories

I guess it's a different library? I'd just put that in the name if so.

The OpenMP library is unfortunately not an amdgcn one. Ideally we want to move amdgcn/bitcode to llvm/lib/amdgcn, but that would require a lot of changes, testings, etc. And it will for sure break a huge amount of ROCm components because most of them have pretty much hard coded path like this.

Downstream PR . Currently some files in downstream PR are not upstreamed because they require other emissary api's to be upstreamed and are non-asan related.
