ARM: fix assert on unpredictable POP instruction.
POP instructions are aliased to the ARM LDM variants but have different syntax.
This caused two problems: we tried to access a non-existent operand to annotate
the '!', and the error message didn't make much sense.
With some vigorous hand-waving in the error message both problems can be
fixed.
