It looks like ifcvt (or rather, can_move_insns_across_p) is doing the right
thing. The problem is that may_trap_or_fault_p returns false for the memory
reference with an out-of-range address based on the frame pointer.

I'll keep thinking about it; no good idea yet about how to fix it without
losing too many optimization opportunities.
