With a compiler that defaults to cmodel medany, pr113206-2.c ends up
generating an extra vsetvli insn.
Set the code model explicitly to medlow to meet the expectation.
This is unfortunately not enough to get the test to a pass on trunk.
It is on gcc-15 and the change is an improvement, but trunk still gets
an unexpected vsetvli even with the change.
Regstrapped on x86_64-linux-gnu along with other patches in this batch;
also tested with targets riscv64-elf and riscv32-elf on the same host,
both trunk and gcc-15. Ok to install?

* gcc.target/riscv/rvv/autovec/pr113206-2.c: Set the expected
code model explicitly.

More tolerance and less prejudice are key for inclusion and diversity.
Excluding neuro-others for not behaving ""normal"" is *not* inclusive!
