[Mesa-dev] [PATCH] glsl: Do not allow scalar types in vector relational functions

[Boyan Ding]

According to OpenGL Shading Language 4.50 spec, Section 8.7 "Vector
Relational Functions", functions of this type do not operate on scalar
types, so remove scalar types from signature definitions to make the
behavior consistent with glslangValidator and other drivers.
