The MC layer instructions have the correct register classes, and
the pseudos don't have any additional operands.

The pseudos we incorrectly going through code in RISCVMCInstLower
that converted LMUL>1 register classes to LMUL1 register class.
This makes the MCInst technically malformed, and prevented the
vl2r.v, vl4r.v, and vl8r.v InstAliases from matching. This accounts
for all of the .ll test diffs.
