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.

	* include/bits/atomic_futex.h [!_GLIBCXX_USE_C99_STDINT_TR1]
	(__atomic_futex_unsigned_base): Remove dependency on
	_GLIBCXX_USE_C99_STDINT_TR1 macro.
	* include/bits/unique_lock.h [!_GLIBCXX_USE_C99_STDINT_TR1]
	(unique_lock): Remove dependency on _GLIBCXX_USE_C99_STDINT_TR1.
	* include/c_global/cstdint [!_GLIBCXX_USE_C99_STDINT_TR1] (intmax_t)

	* include/std/chrono [!_GLIBCXX_USE_C99_STDINT_TR1] (duration)
	(time_point, system_clock, high_resolution_clock, steady_clock): Remove
	dependency on _GLIBCXX_USE_C99_STDINT_TR1 macro.
	(nanoseconds, microseconds, milliseconds, seconds, minutes, hours):
	[!_GLIBCXX_USE_C99_STDINT_TR1]: Define using __INT64_TYPE__ or
	long long when <stdint.h> is not usable.
	* include/std/condition_variable [!_GLIBCXX_USE_C99_STDINT_TR1]
	(condition_variable, condition_variable_any): Remove dependency on
	_GLIBCXX_USE_C99_STDINT_TR1.
	* include/std/future [!_GLIBCXX_USE_C99_STDINT_TR1] (future, promise)
	(packaged_task, async): Likewise.
