Dipshet 98020a02b2 Fix lines on open waters seen at an acute angle (undefined shader derivatives) ...

The water shader's wave-normal lookup sits inside control flow this translator
generates from the guest's predication and jumps, where DXBC derivatives are
undefined: the gradient collapses to zero along the ocean mesh's seams, the LOD
clamps to the finest mip, and grazing Fresnel amplifies that into a bright line.
Computing the gradients in the prologue, where the quad is uniform, restores them.
