[PATCH] D85499: [X86] Canonicalize andnp for bitmask arithmetic

[Keno Fischer via Phabricator via llvm-commits]

loladiro added a comment.

I think that would be fine, but in that case, we should probably get rid of `x86andnp` entirely and just make `(and (not x) y)` canonical everywhere. The supported patterns for these are much the same, so if we have both canonical forms, we're just signing up for double the work.
