lima/ppir: add NIR pass to split varying loads
NIR may emit a single instrinsic to load several packed varyings, but that's suboptimal for Utgard PP for several reasons: - varyings that are used as sampler inputs can be passed using pipeline register with increased precision - we have small number of regs, so using a vec4 regs for storing two vec2 varyings increases reg pressure. Add NIR pass to split a single load into several loads and utilize it in lima. Reviewed-by: Qiang Yu <[email protected]> Signed-off-by: Vasily Khoruzhick <[email protected]>
