On the following testcase, match.pd during GENERIC folding
changes the -1U / x < y into __imag__ .MUL_OVERFLOW (x, y),
but unfortunately unlike for normal calls nothing sets TREE_SIDE_EFFECTS on
the call. There is the process_call_operands function that non-internal
call creation calls and it is usable for internal calls too,
e.g. TREE_SIDE_EFFECTS is derived from checking whether the
call has side-effects (non-ECF_{CONST,PURE}; we have those for internal
calls) and from whether any of the arguments has TREE_SIDE_EFFECTS.
