The linker options we currently use for PGO on Windows are deprecated and should be updated to /GENPROFILE and /USEPROFILE.

No idea whether this will affect the optimization of the results, but it's general goodness anyway to make sure we don't suddenly stop working if/when the compiler drops the old option entirely.
