From: Ian Romanick <ian.d.roman...@intel.com>
For the first declaration below, there will be an ir_variable named
"instance" whose type and whose instance_type will be the same
glsl_type. For the second declaration, there will be an ir_variable
named "f" whose type is float and whose instance_type is B2.
"instance" is an interface instance variable, but "f" is not.
uniform B1 {
float f;
} instance;
uniform B2 {
float f;
};
