This pass tries to remove comparison instructions when possible. For instance,
if you have this code:
sub r1, 1
cmp r1, 0
bz L1

converted to set the same flag, then we can eliminate the "cmp" instruction all

CPSR flag, but need a special suffix ('s') to do so.

Reserve a stack slot if the function adjusts the stack but doesn't
simplify the call frame pseudo instructions. In that situation, the
calculations for estimating the stack size will be way off, leading to
not having an emergency spill slot when we need one. It should be possible
to be more precise about tracking the adjustment values, but not really
necessary for correctness. Upcoming cleanups for PEI in general will
