  [X86][AVX] combineHorizOpWithShuffle - fix valuetype comparison typo.

Ensure we check the valuetypes of all the HOP(SHUFFLE(X,Y),SHUFFLE(X,Y)) shuffle input ops - there was a copy+paste typo (noticed by MSVC analyzer) that meant we were checking the same input from one of the shuffles twice.

I haven't been able to create a test case for this yet - I don't think its currently possible to create a target/faux binary shuffle that scales to a 2x128 shuffle mask from two different value types.
