This patch removes volatile qualifiers from pointer members in mt_allocator.h. It doesn't change function signatures and so should be ABI safe.

Bootstrapped and tested on x86_64-unknown-linux-gnu some time ago.
_M_free and _M_used pointers need not be volatile, they are written
in __pool::_M_initialize() only.

Can you please study a bit libstdc++/24469, before we go ahead with this kind of clean-up? You can start from line # 295 in mt_allocator.cc

Thanks,
Paolo.
