  -----------
  [RISCV] Add coverage for abdu and abds (absolute difference)

Test copied from aarch64 with minimal adaption.  We likely need addition
coverage, but this is a reasonable starting point.

  Log Message:
  -----------
  [RISCV] Add fixed vector coverage for sum-absolute-difference (sad) pattern

This builds on the previously added absolute difference cases, and adds
the reduction at the end.  This is mostly interesting for examining
impact of extend placement when changing the abdu lowering.
