[Vm-dev] Are AlignmentNops actually used?

In my -- admittedly very limited (Squeak ReaderImages simulating ARMv7)
-- tests I've never seen #concretizeAlignmentNops do anything. It does
get called, but it never emits any code. This is because
machineCodeSize=0, so the
0 to: machineCodeSize - 1 by: 4 do:
[:p| self machineCodeAt: p put: 16rE1A00000].
gets no iterations.
Are there cases when this gets called with nonzero machineCodeSize, or
is it a candidate for deletion?
