  -----------
  [X86] Make PreprocessISelDAG create X86ISD::VRNDSCALE nodes with i32 constants instead of i8.

This is the type declared in X86InstrFragmentsSIMD.td. ISel pattern
matching doesn't check so it doesn't matter in practice. Maybe for
SelectionDAG CSE it would matter.

  -----------
  [X86] Truncate immediate to i8 for INTR_TYPE_3OP_IMM8

This is used for DBPSADBW which has a i32 immediate for its
intrinsic and an i8 immediate in tablegen isel patterns.

  Log Message:
  -----------
  [X86] Rename INTR_TYPE_4OP to INTR_TYPE_4OP_IMM8 and truncate immediates to MVT::i8

This makes sure VPTERNLOG is generated with MVT::i8 immediate
as its SDNode declaration in X86InstrFragmentsSIMD.td declares.

  Log Message:
  -----------
  [X86] When manually creating intrinsic nodes in X86ISelLowering, make sure we use getTargetConstant and pointer type for the intrinsic ID.

Doesn't really matter in practice but that's how the nodes are
normally created by SelectionDAGBuilder. So we should match.

Found by temporarily hacking type checks into isel table.
