i386.md (sqrt{s,d}f2_1, [...]): Unify enable constraint with respect to TARGET_SSE...

	* config/i386/i386.md (sqrt{s,d}f2_1, sqrt{s,d}f2_1_sse_only,
	sqrt{s,d}f2_i387): Unify enable constraint with respect to
	TARGET_SSE, TARGET_SSE2, TARGET_USE_FANCY_MATH_387,
	TARGET_SSE_MATH and TARGET_MIX_SSE_I387.
	(sqrt{s,d}f2_1): Rename to *sqrt{s,d}f2_mixed.
	(sqrt{s,d}f2_1_sse_only): Rename to *sqrt{s,d}f2_sse.
	(sqrt{s,d}f2_i387): Rename to *sqrt{s,d}f2_i387.
	(*sqrtextendsfdf2): Also enable for TARGET_MIX_SSE_I387.
	(*sqrtextend?f?f2): Rename to *sqrtextendsfdf2_i387.
