[PATCH] D25361: [libcxx] Add the missing limits.h header

[Richard Smith via cfe-commits]

rsmith added a comment.

I only skipped this one because it seemed pointless to me. I have no objection to providing it, and this change makes perfect sense if libc++ wants to guarantee that `<__config>` is included whenever any standard C++ header is included.
