[X86][AVX] Ensure broadcast loads respect dependencies
To allow broadcast loads of a non-zero'th vector element, lowerVectorShuffleAsBroadcast can replace a load with a new load with an adjusted address, but unfortunately we weren't ensuring that the new load respected the same dependencies.
This patch adds a TokenFactor and updates all dependencies of the old load to reference the new load instead.
Bug found during internal testing.
