Fix biased integer arithmetic
The Ada compiler uses a biased representation when a size clause reserves
fewer bits than normal either for the lower or for the upper bound.
gcc/ada/ChangeLog:
* gcc-interface/trans.c (build_binary_op_trapv): Convert operands
to the result type before doing generic overflow checking.
gcc/testsuite/ChangeLog:
* gnat.dg/bias2.adb: New test.
