Fix RISC-V test after recent vectorizer changes

Richi's patch to fix costing of permuted contiguous loads changed the code
generation for pr122445.c in the testsuite.  After reviewing the code, it looks
clearly better to me -- essentially covering 2X as many elements per vector op
with fewer total vector ops in the end (without resulting to LMUL > 1).

I've verified this fixes the overnight regressions seen on riscv{32,64}-elf.
The bootstrap and regression tests are in flight, but won't finish for many
more hours.
