libstdc++: Reduce <atomic> dependency on _GLIBCXX_USE_C99_STDINT_TR1

Browse source 
Since r9-2028-g8ba7f29e3dd064 we've defined most of <cstdint>
unconditionally, so we can do the same for most of the std::atomic
aliases such as std::atomic_int_least32_t.

The only aliases that need to depend on _GLIBCXX_USE_C99_STDINT_TR1 are
the ones for the integer types that are not guaranteed to be defined,
e.g. std::atomic_int32_t.

libstdc++-v3/ChangeLog:

	* include/std/atomic (atomic_int_least8_t, atomic_uint_least8_t)
	(atomic_int_least16_t, atomic_uint_least16_t)
	(atomic_int_least32_t, atomic_uint_least32_t)
	(atomic_int_least64_t, atomic_uint_least64_t)
	(atomic_int_fast16_t, atomic_uint_fast16_t)
	(atomic_int_fast32_t, atomic_uint_fast32_t)
	(atomic_int_fast64_t, atomic_uint_fast64_t)
	(atomic_intmax_t, atomic_uintmax_t): Define unconditionally.
	* testsuite/29_atomics/headers/stdatomic.h/c_compat.cc: Adjust.
