  Log Message:
  -----------
  [RISCV] Migrate zvqdotq reduce matching to use partial_reduce infrastructure (#142212)

This involves a codegen regression at the moment due to the issue
described in 443cdd0b, but this aligns the lowering paths for this case
and makes it less likely future bugs go undetected.
