*	Ensure that the backend no longer emits unnecessary vector insert instructions	Andrea Di Biagio	2013-12-10
	immediately after SSE scalar fp instructions like addss or mulss. Added patterns to select SSE scalar fp arithmetic instructions from a scalar fp operation followed by a blend. For example, given the following code: __m128 foo(__m128 A, __m128 B) { A[0] += B[0]; return A; } previously we generated: addss %xmm0, %xmm1 movss %xmm1, %xmm0 now we generate: addss %xmm1, %xmm0 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196925 91177308-0d34-0410-b5e6-96231b3b80d8
