[X86] getTargetVShiftNode - remove shift-by-constant handling.
Move shift-by-constant handling and move it into its only user (VSHIFT intrinsics lowering).
This is some prep-work for getTargetVShiftNode to no longer take a scalar shift amount - we're introducing temporary ISD::EXTRACT_VECTOR_ELT nodes via SelectionDAG::getSplatValue to accommodate this which can cause various issues, including unnecessary scalarization and xmm->gpr->xmm transfers, and causes problems for 32-bit codegen if we fail to remove an (illegal) i64 scalar extracted from a (legal) vXi64 vector.
