[PATCH] testsuite: Fix up tree-ssa/divide-7.c testcase [PR95424]

[Jakub Jelinek via Gcc-patches]

Hi!

This test fails everywhere, because ? doesn't match literal ?.
It should use \\? instead.  I've also changed those .s in there.
Tested on x86_64-linux (-m32/-m64) and powerpc64le-linux, ok for trunk?
