Craig Topper 576d81baa5 [RISCV] Use REG_SEQUENCE/EXTRACT_SUBREG to move between individual GPRs and GPRPair. (#85887) ...

Previously we used memory like we do to move between GPRs and FPR64 with
the D extension on RV32.

We can instead use REG_SEQUENCE/EXTRACT_SUBREG to inform register
allocation how to do the copy without memory.
