The CGProfilePass needs to be run late, after FLTO, in order to populate the compiled LTO object file with the PGL section, currently, it is being run during the initial compilation stage (LTO-prelink) to produce the bitcode files to be consumed by the linker.

TLTO is not affected as the passes are added (correctly) via a different path

Adjust the passes so that the PGL section is produced correctly for FLTO.
