i965/nir: Enable NIR lowering of txf and rect offsets

This fixes the following piglit tests on gen6+:

tex-miplevel-selection textureProjGradOffset 2DRect
tex-miplevel-selection textureGradOffset 2DRect
tex-miplevel-selection textureGradOffset 2DRectShadow
tex-miplevel-selection textureProjGradOffset 2DRect_ProjVec4
tex-miplevel-selection textureProjGradOffset 2DRectShadow
