[asan] Turn on Mach-O global metadata liveness tracking by default
This patch turns on the metadata liveness tracking since all known issues
have been resolved. The future has been implemented in
https://reviews.llvm.org/D16737 and enables support of dead code stripping
option on Mach-O platforms.
As part of enabling the feature, I also plan on reverting the following
patch to compiler-rt:
