re PR target/78614 (ICE error: invalid rtl sharing found in the insn (verify_rtx_sharing) gcc/emit-rtl.c:2743)
PR target/78614
* rtl.c (copy_rtx): Don't clear used flag here.
(shallow_copy_rtx_stat): Clear used flag here unless code the rtx
is shareable.
* simplify-rtx.c (simplify_replace_fn_rtx): When copying rtx with
'E' in format, copy all vectors.
* emit-rtl.c (copy_insn_1): Don't clear used flag here.
* valtrack.c (cleanup_auto_inc_dec): Likewise.
* config/rs6000/rs6000.c (rs6000_frame_related): Likewise.
