	* math/math.h (isgreater, isgreaterequal, isless, islessequal,
	islessgreater, isunordered): Use builtins if available.
	* sysdeps/i386/fpu/bits/mathinline.h: Don't define via builtins.
	* sysdeps/m68k/fpu/bits/mathinline.h: Likewise.
	* sysdeps/powerpc/fpu/bits/mathinline.h: Likewise.
	* sysdeps/sparc/fpu/bits/mathinline.h: Likewise.
	* sysdeps/x86_64/fpu/bits/mathinline.h: Likewise.
	* sysdeps/alpha/fpu/bits/mathinline.h (isgreater, isgreaterequal,
	isless, islessequal, islessgreater): Remove; use default.
	(isunordered): Convert inputs to double.
