testsuite: remove -fwrapv from signbit-5.c
The meaning of the testcase was changed by passing it -fwrapv. The reason for
the test failures on some platform was because the test was testing some
implementation defined behavior wrt INT_MIN in generic code.
Instead of using -fwrapv this just removes the border case from the test so
all the values now have a defined semantic. It still relies on the handling of
shifting a negative value right, but that wasn't changed with -fwrapv anyway.
The -fwrapv case is being handled already by other testcases.
gcc/testsuite/ChangeLog:
* gcc.dg/signbit-5.c: Remove -fwrapv and change INT_MIN to INT_MIN+1.
