It's done here as we're trying to match various x86 specific load patterns - basic consecutive loads, 'masked' loads with undef/zeros that get blended out, loads with all upper vector elements set to zero. I'm also hoping to add broadcast/vector_broadcast soon (possibly ZERO_EXTEND_VECTOR_INREG as well).
