Correct tinyness handling in long-double and float y0/y1.
	With help from Joseph Myers.
	* sysdeps/ieee754/flt-32/e_j0f.c (__ieee754_y0f): Adjust tinyness
	cutoff to 2**-13.
	* sysdeps/ieee754/flt-32/e_j1f.c (__ieee754_y1f): Adjust tinyness
	cutoff to 2**-25.
	* sysdeps/ieee754/ldbl-128/e_j0l.c (U0): New constant.
	( __ieee754_y0l): Avoid arithmetic underflow when 'x' is very
	small.
	* sysdeps/ieee754/ldbl-128/e_j1l.c (__ieee754_y1l): Likewise.
	* math/libm-test.inc (y0_test): New tests.
	(y1_test): New tests.
	* sysdeps/i386/fpu/libm-test-ulps: Update.
	* sysdeps/x86_64/fpu/libm-test-ulps: Update.
	* sysdeps/sparc/fpu/libm-test-ulps: Update.
