Add missing checks for _GLIBCXX_USE_C99_STDINT_TR1 

The throw_allocator extension depends on <tr1/random> which depends on
_GLIBCXX_USE_C99_STDINT_TR1.

The Transactional Memory support uses fixed-width integer types from
<stdint.h>.

	* include/ext/throw_allocator.h [!_GLIBCXX_USE_C99_STDINT_TR1]
	(random_condition, throw_value_random, throw_allocator_random)
	(std::hash<throw_value_random>): Do not define when <tr1/random> is
	not usable.
	* src/c++11/cow-stdexcept.cc [!_GLIBCXX_USE_C99_STDINT_TR1]: Do not
	define transactional memory support when <stdint.h> is not usable.
