[PATCH] [PR116831] match.pd: Check trunc_mod vector obtap before folding.

As in https://gcc.gnu.org/pipermail/gcc-patches/2024-September/663185.html, this patch guards the simplification x / y * y == x -> x % y == 0 in match.pd for vector types by a check for: 1) Support of the mod optab for vectors OR 2) Application before vector lowering for non-VL vectors. The patch
