This build re-uses the PGO profile from the win64 build in the win64-aarch64-shippable-no-eme part of the aarch64 build. Even though the profile isn't generated on the smae platform, we still get enough of a performance win to make this worthwhile. Note that the pgo_flags() in configure need to be tweaked slightly since we don't supprt the -fprofile-generate flag for aarch64 (we don't build the clang_rt.profile lib there). So we always want to return the flags namespace to make sure we get the use_* versions of flags, which we do need.
