  Changed paths:
    M llvm/lib/Target/RISCV/RISCVISelLowering.cpp
    M llvm/lib/Target/RISCV/RISCVISelLowering.h
    M llvm/lib/Target/RISCV/RISCVInstrInfo.td

  Log Message:
  [RISCV] Don't emit LUI/ADDI MachineSDNodes from getAddr

Instead add RISCVISD opcodes that will be selected to LUI/ADDI
during isel.

I'm looking into maybe moving doPeepholeLoadStoreADDI into isel.
Having the ADDI as a RISCVISD node will make it visible to isel.
