[PATCH] D62063: CMake changes to get Windows self-host with PGO working

[Russell Gallop via Phabricator via llvm-commits]

russell.gallop updated this revision to Diff 200469.
russell.gallop added a comment.

Handle -fprofile-generate and -fcs-profile-generate options for self hosting as well.

This highlights two other problems with using those options for Windows self host builds.
1). -fprofile-generate and -fcs-profile-generate need clang_rt.profile adding with --dependent-lib in the driver (like https://reviews.llvm.org/D61742). I'll create a separate review for that.
2). Self hosting with -fprofile-generate hits a crash building CrashRecoveryContext.cpp. I'll try to report this.

But I believe that the cmake changes are okay.
