Since most (all) other insn-specific tests are different in this regard,
I wonder whether it is on purpose that the actual encodings get omitted
here (or to be precise, skipped by way of using .* ). Since these tests
serve as both assembler and disassembler ones, I think checking that the
correct encodings get produced (and consumed) would be at least helpful.
