[PATCH] D61245: [X86][SSE] isHorizontalBinOp - add support for target shuffles

[Simon Pilgrim via Phabricator via llvm-commits]

Herald added a project: LLVM.

Add target shuffle decoding to isHorizontalBinOp as well as ISD::VECTOR_SHUFFLE support.

This does mean we can go through bitcasts so we need to bitcast the extracted args to ensure they are the correct type

Fixes PR39936 and should help with PR39920/PR39921
