[X86][AVX] combineX86ShuffleChainWithExtract - add number of non-zero extract_subvectors to the combine depth

This better accounts for the cost/benefit of removing extract_subvectors from the shuffle and will be more useful in future patches.

The vpermq predicate regression will be fixed shortly.
