#2877 (Regression) Incorrect overflow warning when adding two numbers

[Alan Cox]

If you pass an 8bit constant of 233 as a uint8_t argument it works. If you pass 192 + 41 as the argument it warns you about overflows in constant conversions. 3.6.x does not have this problem. 3.7 does.

The generated code fortunately is correct.

I still see this issue as of [r13822].

Execution on snapshot r17038 confirms the false warning, but calculates 233 correctly.
