So actually I'm gravitating towards calling all that instruction
"massaging" code with a single prefix to denote this comes from the insn
decoder/handler/whatever...

I.e.,

	"insn-decoder: x86: invalid register type"

or

	"inat: x86: invalid register type"

or something to that effect.

I mean, If we're going to grow our own - as we do, apparently - maybe it
all should be a separate entity with its proper name.

Hmm.
