[libcxx] Add the missing limits.h header

Authored by rmaprath on Oct 7 2016, 3:16 AM.



The implementation of [depr.c.headers] in D12747 introduced the necessary
C headers into libc++. This patch adds one more missing headers: limits.h

We spotted this due to a failing C++03 test [limits_h.pass.cpp] in our libc++
configuration; when the limits.h header is included from a C++ program, it now
bypassed the __config header and went directly into the underlying C library's
limits.h header, which is problematic for us because we use __config header to
configure the underlying C library's behaviour when used from a C++ context.

This looks fine to me, but since @rsmith added all the other C headers, I'd like him to weigh in.

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.
