[committed] libstdc++: Simplify typedefs by using __UINTPTR_TYPE__

[Jonathan Wakely via Gcc-patches]

Tested powerpc64le-linux, pushed to trunk.


libstdc++-v3/ChangeLog:

        * include/ext/pointer.h (_Relative_pointer_impl::_UIntPtrType):
        Rename to uintptr_t and define as __UINTPTR_TYPE__.
