  -----------
  AMDGPU: Minor improvement and cleanup for waterfall loop generation (#111886)

First, ReadlanePieces should be in the scope of each MachineOperand. It
is not correct if we declare in a outer scope without clearing after the
use for a MachineOperand.
Additionally, we do not need the OrigBB argyment for
emitLoadScalarOpsFromVGPRLoop, since MachineFunction (the only use) can
be obtained from LoopBB (or BodyBB).
