There was some unfortunate interaction between VSPLAT and BITCAST related to the selection of constant vectors (coming from selecting shuffles). Introduce VSPLATW that always splats a 32-bit word, and can have arbitrary result type (to avoid BITCASTs of VSPLAT). Clean up the previous selection of BITCAST/VSPLAT. llvm-svn: 330471
