i386: move ULPs to i686/multiarch and regenerate new ones for i386

The i386 ULPs are actually the i686/multiarch ones. The i686/multiarch
float ULPs are more precise as the SSE2 version (when available) uses
double for the cosf and sinf functions.

On the other hand the higher precision of the x86 FPU improves the
precision for a few other math functions.

	* sysdeps/i386/i686/multiarch/fpu/libm-test-ulps: ...here.
	* sysdeps/i386/fpu/libm-test-ulps: Regenerate.
