For this test, wouldn't it be better to check that the cop name (cN)
is the last 2 chars of the insn name? There are no exceptions to that
rule in the opcodes table that I can currently see (of operations
which use these operand types).

If I were creating the new files, I'd have goten them names a little
bit more consistent, but I don't care a lot. 8-)
A bit of an aside, but do you know why the c3 ops seem to generate
delay slot nops? (That seems a little ... non-intuitive to me.)
