[LLVM] Fix LLVM_CSPROFILE_FILE_PATTERN not being used

[tambre]

Summary

Seems to be a copy-paste error due to which LLVM_CSPROFILE_FILE_PATTERN isn't actually used anywhere.

Just discovered that only -fprofile-instr-generate supports taking a pattern, but others don't. Seems inconsistent. I'd like to use a pattern not a directory with -fcs-profile-generate too.

         append("-fprofile-generate=\"${LLVM_PROFILE_DATA_DIR}\""
