*	acos.s fix: use the formula acos(x) = atan2(sqrt(1-x),sqrt(1+x))	nsz	2012-03-22	1	-3/+1
\| \| \| \| \| \| \|	the old formula atan2(1,sqrt((1+x)/(1-x))) was faster but could give nan result at x=1 when the rounding mode is FE_DOWNWARD (so 1-1 == -0 and 2/-0 == -inf), the new formula gives -0 at x=+-1 with downward rounding.
*	x86_64 math asm, long double functions only	Rich Felker	2012-03-20	1	-0/+20
	this has not been tested heavily, but it's known to at least assemble and run in basic usage cases. it's nearly identical to the corresponding i386 code, and thus expected to be just as correct or just as incorrect.
