Nadav Rotem d1a79136e3 AVX: We lower VECTOR_SHUFFLE and BUILD_VECTOR nodes into vbroadcast instructions
using the pattern (vbroadcast (i32load src)). In some cases, after we generate
this pattern new users are added to the load node, which prevent the selection
of the blend pattern. This commit provides fallback patterns which perform
in-vector broadcast (using in-vector vbroadcast in AVX2 and pshufd on AVX1).
