thibaut 2ecbbe40a3 fix(shader): keep direct VGPR accesses in SSA when the window has only relative reads ... A program that uses relative VGPR addressing placed every register from the lowest relatively addressed one upward in the window array, so even direct accesses became array loads and stores. A descriptor spilled with v_writelane and restored with v_readlane then lost its definition, and resource analysis refused GetSamplerResource with ReadLane(LoadVectorWindow(Immediate)) (GTA V, PPSA04264, shader 0x25a889400). When the program has no indexed writes (v_movreld, v_movrelsd, v_swaprel), direct accesses stay SSA registers and each direct write is mirrored into the window for the relative reads.
