tl;dr: Teach Clang to work around g++ changing its workaround to glibc's

The C99 standard says that certain macros in <stdint.h>, such as SIZE_MAX,
should not be defined when the header is included in C++ mode, unless
__STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS are defined. The C++11 standard
says "Thanks, but no thanks" and C11 removed this rule, but various C library
implementations (such as glibc) follow C99 anyway.

g++ prior to 4.8 worked around the C99 / glibc behavior by defining
__STDC_*_MACROS in <cstdint>, which was incorrect, because <stdint.h> is
supposed to provide these macros too. g++ 4.8 works around it by defining
__STDC_*_MACROS in its builtin <stdint.h> header.
