x86: use VPTERNLOG also for certain andnot forms
When it's the memory operand which is to be inverted, using VPANDN*
requires a further load instruction. The same can be achieved by a
single VPTERNLOG*. Add two new alternatives (for plain memory and
embedded broadcast), adjusting the predicate for the first operand
accordingly.
Two pre-existing testcases actually end up being affected (improved) by
the change, which is reflected in updated expectations there.
