NOP instructions are pseudo-instructions. We should not have them explicitly in
...
our representation, since they are usually special cases of already-existing
instructions.
This abstracts away methods that let a pass create and verify a NOP instruction,
without relying on a `NOP' enum to be in existence in the target's instruction
info descriptor.
