[PATCH] D13182: [compiler-rt] Fix Clang-tidy modernize-use-nullptr warnings in lib/sanitizer_common headers, unify closing inclusion guards

[Kostya Serebryany via llvm-commits]

kcc added a comment.

You've run clang-tidy to make the code better. 
But we don't have it as a pre-commit check and so the following commits will 
make the code clang-tidy-unclean again (i.e regress).
