This PR resubmits the changes from #136098, which was previously reverted due to a build failure during the linking stage: ``` undefined reference to `llvm::DebugInfoCorrelate' undefined reference to `llvm::ProfileCorrelate' ``` The root cause was that `llvm/lib/Frontend/Driver/CodeGenOptions.cpp` references symbols from the `Instrumentation` component, but the `LINK_COMPONENTS` in the `llvm/lib/Frontend/CMakeLists.txt` for `LLVMFrontendDriver` did not include it. As a result, linking failed in configurations where these components were not transitively linked. ### Fix: This updated patch explicitly adds `Instrumentation` to `LINK_COMPONENTS` in the relevant `llvm/lib/Frontend/CMakeLists.txt` file to ensure the required symbols are properly resolved. --------- Co-authored-by: ict-ql <168183727+ict-ql@users.noreply.github.com> Co-authored-by: Chyaka <52224511+liliumshade@users.noreply.github.com> Co-authored-by: Tarun Prabhu <tarunprabhu@gmail.com>

! Tests for -fprofile-generate and -fprofile-use flag compatibility. These two

!

! -fprofile-generate Generates the profile file ./default.profraw

! -fprofile-use=<dir>/file Uses the profile file <dir>/file
