[compiler-rt] r281970 - tsan: check more addresses in CheckShadowMapping

[Dmitry Vyukov via llvm-commits]

Reverted in 281992

I don't have access to aarch64/vma42 machine to fix it reliably.
It would be great to be able to test _all_ mappings for all VMAs on
any platform as a unit test. But that will require large refactoring
of tsan_platform.h... which will in turn require access to all
platforms to ensure that refactoring does not break something...
