Already when reading Michael's v1 comment I wondered: How's handling of
multiple comments going to work? Surely we want to switch the present
%rip-relative operand printing to the new cappend_*() model. Hence both
that and an immediate may want to have a comment added. Presumably those
would want to appear in the same order as the operands, which are
printed in different order for AT&T vs Intel syntax.
