This change addresses a gap in the handling of PGO file names for clang-cl only. Discovered with the Rust project, where changing the PGO handing did not force a cache miss.

Resolves #2964

Both the missing commands for instrumenting and using profile data have been added.
Simple test to validate flag support included.
