It is. To be honest I was undecided if we should have it or for now
just replace the old isLabel() with isLabel() || isCFIInstruction(). I
am also suspicious of the code that is handling the cfi instruction
specially. It seems that the best representation would be to bundle it
with some real instruction. If a spill is moved, a cfi instruction
should be moved with it, no?

I picked the name mostly at random. Both labels and cfi instructions
don't exist "for real", their are just a position in the code we know
something special about.

Cheers,
Rafael
