This fixes the following dEQP tests:
-
dEQP-GLES3.functional.shaders.operator.unary_operator.minus.lowp_uvec2_fragment
-
dEQP-GLES3.functional.shaders.operator.unary_operator.minus.lowp_uvec4_fragment
-
dEQP-GLES3.functional.shaders.operator.unary_operator.minus.mediump_uvec2_fragment
-
dEQP-GLES3.functional.shaders.operator.unary_operator.minus.mediump_uvec4_fragment
