Vedant Kumar 426fd51c83 [InstrProf] Add support for dead_strip+live_support functionality ... On Darwin, marking a section as "regular,live_support" means that a symbol in the section should only be kept live if it has a reference to something that is live. Otherwise, the linker is free to dead-strip it. Turn this functionality on for the __llvm_prf_data section. This means that counters and data associated with dead functions will be removed from dead-stripped binaries. This will result in smaller profiles and binaries, and should speed up profile collection. Tested with check-profile, llvm-lit test/tools/llvm-{cov,profdata}, and check-llvm.
