[PATCH] Fix 69845


In PR68142 you added a check for overflow + __INT_MIN__.
I can't figure out why the check for __INT_MIN__, except
that it seems specific to the test case you examined.

And indeed, this test case shows how things go wrong
with other distributed folding leading to overflow.

I added two tests, one signed, one unsigned.  The second
verifies that we do still fold for the defined-overflow case.

Ok?
