* fold-const.c (fold_plusminus_mult_expr): If the factored
factor may be zero use a wrapping type for the inner operation.
* tree-tailcall.c (independent_of_stmt_p): Pass in to_move bitmap
and handle moved defs.
(process_assignment): Properly guard the unary op case. Return a
tri-state indicating that moving the stmt before the call may allow
to continue. Pass through to_move.
(find_tail_calls): Handle moving unrelated defs before
the call.
* c-c++-common/ubsan/pr66313.c: New testcase.
* gcc.dg/tree-ssa/loop-15.c: Adjust.
