2015-03-30	math: fix x86_64 and x32 asm not to use sahf instruction	Szabolcs Nagy	1	-2/+2
	Some early x86_64 cpus (released before 2006) did not support sahf/lahf instructions so they should be avoided (intel manual says they are only supported if CPUID.80000001H:ECX.LAHF-SAHF[bit 0] = 1). The workaround simplifies exp2l and expm1l because fucomip can be used instead of the fucomp;fnstsw;sahf sequence copied from i386. In fmodl and remainderl sahf is replaced by a simple bit test. (cherry picked from commit a732e80d33b4fd6f510f7cec4f5573ef5d89bc4e)
