[v2,0/2] RISC-V: add option -m(no-)autovec-segment

Rebased to squash Edwin's fixup into Greg's patch. Split out the middle-end
change and xfailed the associated testcase so the second patch can land
seperately.

Relying on pre-commit CI for full testing.

Greg McGary (2):
  RISC-V: add option -m(no-)autovec-segment
  Prevent divide-by-zero
