Fix tests for PR 106537.
This patch fixes the tests for PR 106537 (support for
-W[no]-compare-distinct-pointer-types) which were expecting the
warning when checking for equality/inequality of void pointers with
non-function pointers.
gcc/testsuite/ChangeLog:
PR c/106537
* gcc.c-torture/compile/pr106537-1.c: Comparing void pointers to
non-function pointers is legit.
* gcc.c-torture/compile/pr106537-2.c: Likewise.
