PATCH: Update longlong.h from GCC 4.7.0

[H.J. Lu]

Hi,

This patch updates longlong.h from GCC 4.7.0 so that we always use
__builtin_clzll and __builtin_ctzll for x86-64 DImode to support x32.
OK to install?

Thanks.

	* stdlib/longlong.h (count_leading_zeros): Use long long builtin
	for x86-64.
	(count_trailing_zeros): Likewise.
