New Revision: 263003

URL: https://gcc.gnu.org/viewcvs?rev=263003&root=gcc&view=rev
Modify some library internals to work without <stdint.h>

std::__detail::__clp2 used uint_fast32_t and uint_fast64_t without
checking _GLIBCXX_USE_C99_STDINT_TR1 which was a potential bug. A
simpler implementation based on the new std::__ceil2 code performs
better and doesn't depend on <stdint.h> types.

std::align and other C++11 functions in <memory> where unnecessarily
missing when _GLIBCXX_USE_C99_STDINT_TR1 was not defined.

	* include/bits/hashtable_policy.h (__detail::__clp2): Use faster
	implementation that doesn't depend on <stdint.h> types.
	* include/std/memory (align) [!_GLIBCXX_USE_C99_STDINT_TR1]: Use
	std::size_t when std::uintptr_t is not usable.
	[!_GLIBCXX_USE_C99_STDINT_TR1] (pointer_safety, declare_reachable)
	(undeclare_reachable, declare_no_pointers, undeclare_no_pointers):
	Define independent of _GLIBCXX_USE_C99_STDINT_TR1.
