Revisit some -Wuseless-cast changes.

Browse Source 
* lib/fstrcmp.c (fstrcmp_free_resources, fstrcmp_bounded): Use a
compound literal to convert to uintptr_t.
* lib/wait-process.c (wait_subprocess): Use a compound literal to
convert to int.
* lib/sigsegv.c: Revert last change. Instead, disable -Wuseless-cast
in this compilation unit.
* tests/jit/test-cache.c: Likewise.
* tests/test-limits-h.c: Disable -Wuseless-cast warnings also for
gcc 14, 15.
