  Changed paths:
    M llvm/lib/CodeGen/SelectionDAG/StatepointLowering.cpp
    A llvm/test/CodeGen/X86/statepoint-no-extra-const.ll

  Log Message:
  -----------
  Remove the additional constant which requires an extra register for statepoint lowering.

The newly-created constant zero will need an extra register to hold it
in the current statepoint lowering implementation. Remove it if there
exists one.
