glsl: Match unnamed record types across stages.
Unnamed record types are assigned to separate types per stage, e.g. if
uniform struct { ... } a;
is defined in both vertex and fragment shader, two separate types will
result with different names. When linking the shader, this results in a
type conflict. However, there is no reason why this should not be
allowed according to GLSL specifications. Compare and match record types
when linking shader stages to avoid this conflict.
