  Log Message:
  -----------
  [RISCV] Skip unrelated COPY during Zdinx/P instruction generation in RISCVMoveMerge (#200219)

`findMatchingInstPair` returned early on the first non-matching `COPY`,
which could miss a valid later `COPY` pair.

Update the scan to continue past non-matching `COPY` instructions and
only apply existing dependency checks when a lane match is found.
