PR bootstrap/51796
* combine.c (distribute_notes): If i3 is a noreturn call,
allow old_size to be equal to args_size and make sure the
noreturn call gets REG_ARGS_SIZE note.
* expr.c (fixup_args_size_notes): Put REG_ARGS_SIZE notes
on noreturn calls even when the delta is 0.

* gcc.dg/pr51796.c: New test.
