Twiddling it is, then (pending approval ;-)
The pr118182-2.c testcase backported from gcc-15 depended on the late
combine pass after register allocation to substitute the zero constant
into the pred_broadcast to get to the expected vmv.s.x instruction.
Without that pass, we get a mfmv.s.f instead. Expect that on gcc-14.
Tested both riscv64-elf and riscv32-elf on x86_64-linux-gnu.
Ok for gcc-14?

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