After this change:

To be more precise, in this line:
https://github.com/llvm/llvm-project/blob/d2a710ea784eea43c63e3831224de6355f1e4a6f/clang/lib/Frontend/CompilerInvocation.cpp#L3587

We have a problem during second compilation of user kernel via opencl-clang in the same process. When we hit this place two times - it will abort the compilation, because we are trying to assign the same flag twice which is wrong.

message error:
clang (LLVM option parsing): for the --pgo-warn-misexpect option: may only occur zero or one times!
