V implies Zvl128b, but a lot of the fixed vector tests also redundantly specify -riscv-v-vector-bits-min=128. This patch removes them where there isn't another minimum vlen being tested for, and for cases where Zve* is being used Zvl128b was added to maintain the old test diff (and because an awkward vlen probably isn't interesting to test for). Other places where -risc-v-vector-bits-min were being used were replaced with Zvl.
