Fix and reapply IR PGO support for Flang (#142892)
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.
