This is particularly useful in cases where register coalaesce is unlikely to succeed because the LOAD_PAYLOAD isn't a plain copy -- E.g. when a LOAD_PAYLOAD is shuffling the contents of a barycentric vector in order to transform it into the PLN layout. This prevents the following shader-db regressions (including SIMD32 programs) in combination with the interpolation rework part of this series.
