Summary: When inserting an element that's coming from a vector load or a broadcast of a vector (or scalar) load, combine the load into the insertps instruction. Added PerformINSERTPSCombine for the case where we need to fix the load (load of a vector + insertps with a non-zero CountS). Added patterns for the broadcasts. Also added tests for SSE4.1, AVX, and AVX2.
