Add {add,sub,mul}_overflow detection when one operand is a constant
We were missing 64-bit signed mul_overflow on 32-bit platforms and in
those where we did have it, the detection was awful (both for signed and
for unsigned). So if one of the parameters is a constant, we can
simplify the code generated.
