Nick Lewycky 6977e79526 Support pointer comparisons against constants, when looking at the inline-cost

savings from a pointer argument becoming an alloca. Sometimes callees will even
compare a pointer to null and then branch to an otherwise unreachable block!
Detect these cases and compute the number of saved instructions, instead of
bailing out and reporting no savings.
