[Bug target/35634] [avr] result of char promotion comes out of CHAR_MIN/MAX

Actually, there is no undefined behaviour here, as long as CHAR_MAX < INT_MAX
no overflow occurs.  c++ is the same as c = (int)c + 1 (when ignoring the
result), and the conversion from int to char is implementation defined.  For
gcc the result of such a conversion is always in the range of the target type.
