re PR rtl-optimization/80491 (Compiler regression for long-add case.)

PR rtl-optimization/80491
* ifcvt.c (noce_process_if_block): When looking for x setter
with missing else_bb, don't check only the insn right before
cond_earliest, but look for the last insn that x is modified in
within the same bb.
