Support _Float128 in ldbl-96 bits/iscanonical.h.

This patch adds _Float128 support to the ldbl-96 bits/iscanonical.h,
as needed for x86_64 / x86 / ia64 support of _Float128.

Tested for x86_64 (in conjunction with float128 patches).

	* sysdeps/ieee754/ldbl-96/bits/iscanonical.h
	[__HAVE_DISTINCT_FLOAT128] (__iscanonicalf128): New macro.
