* flow.c (mark_set_1, case PARALLEL): Now case; rework to allow
entry to be EXPR_LIST.
* rtlanal.c (reg_overlap_mentioned_p): Allow PARALLEL in SET to
be an EXPR_LIST (but not null, which other code doesn't allow).
(note_stores): Properly handle PARALLEL in SET.
Recursively call for top-level PARALLEL.
* sched-deps.c (sched_analyze_1): Handle EXPR_LIST in PARALLEL in SET.
* sched-rgn.c (check_live_1, update_live_1): Likewise.
