[PATCH 4/8] Add missing checks for _GLIBCXX_USE_C99_STDINT_TR1

[jwakely]

From: Jonathan Wakely <jwak...@redhat.com>

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.
