 PR rtl-optimization/61094
 * ree.c (combine_reaching_defs): Do not reextend an insn if it
 was marked as do_no_reextend. If a copy is needed to eliminate
 an extension, then mark it as do_not_reextend.

 eliminated extension requires widening a copy created for elimination
 of a prior extension.

 for a destination register does not change when we widen it.
