[PATCH] D11948: Add some macros to abstract marking of parameters as "not null", and use them in <cstring>

[Marshall Clow via cfe-commits]

mclow.lists updated this revision to Diff 33624.
mclow.lists added a comment.

Fixed a typo in the patch for `strncmp`, and added a macro `_LIBCPP_HAS_NO_NONNULL` to allow people to disable these checks.

Marked them as disabled for non-clang and non-gcc compilers.
