they're like the non-'i' variants of similar name, but operate on
'i'nstructions (i.e., code that you're likely to execute).

IIRC -- and i wasn't around that long ago 8-) -- they date back to the
time of separate I and D spaces, i.e., they operated on the
instruction space.

They should make sure the result of their operation is properly
executable (i.e., flush icache if necessary after store).
