Remove <chrono> dependency on _GLIBCXX_USE_C99_STDINT_TR1

Remove <chrono> dependency on _GLIBCXX_USE_C99_STDINT_TR1

By adding fallback definitions of std::intmax_t and std::uintmax_t it's
possible to define <ratio> without _GLIBCXX_USE_C99_STDINT_TR1. This in
turn allows most of <chrono> to be defined, which removes the dependency
on _GLIBCXX_USE_C99_STDINT_TR1 for all of the C++11 concurrency features.

The compiler defines __INTMAX_TYPE__ and __UINTMAX_TYPE__
unconditionally so it should be safe to rely on them.
