[PATCH] testsuite: Add -fwrapv to signbit-5.c

[Torbjörn SVENSSON]

Ok for trunk and releases/gcc-14?

Verified this on x86_64 and arm-none-eabi.
Don't know if the other "truth type" dg-lines can be removed as well.

--

On Cortex-M55 with MVE, the test case fails due to -INT_MAX being
undefined. Adding -fwrapv solves the issues.

Regtested on x86_64-pc-linux and arm-none-eabi for
Cortex-M0/M3/M4/M7/M33/M55/M85/A7.

gcc/testsuite/ChangeLog:

	* gcc.dg/signbit-5.c: Add -fwrapv and remove x86 exception.
