Extend VPRecipeWithIRFlags to also manage predicates for compares. This
allows removing the custom ICmpULE opcode from VPInstruction which was a
workaround for missing proper predicate handling.

This simplifies the code a bit while also allowing compares with any
predicates. It also fixes a case where the compare predixcate wasn't
printed properly for VPReplicateRecipes.
