[Mesa-dev] [PATCH v2 1/1] i965: add opportunistic behaviour to opt_vector_float()

opt_vector_float() transforms several scalar MOV operations to a single vectorial MOV. This is done when those MOV covers all the components of the destination register. So something like: mov vgrf3.0.xy:D, 0D mov vgrf3.0.w:D, 1065353216D mov vgrf3.0.z:D, 0D is transformed in: mov vgrf3.0:F,
