But if it starts with OPCODE_ you know what it is - an opcode.
JMP32_INSN_OPCODE can first be shortened to JMP32_OPCODE and then having
instruction mnemonic start the macro name doesn't show they belong to
the same type of things. Ditto for the insn size.

But I'm way too busy to bikeshed so whatever...
