[PATCH 2/3] Use _GLIBCXX_THROW macro in bitmap_allocator

[Jonathan Wakely]

This header should use _GLIBCXX_THROW to make it C++17-friendly.

        * include/ext/bitmap_allocator.h (bitmap_allocator::_S_refill_pool)
        (bitmap_allocator::_M_allocate_single_object)
        (bitmap_allocator::_M_get): Use _GLIBCXX_THROW macro.

Tested powerpc64le-linux, committed to trunk.
