    mesa: Handle binding of uniforms to image units with glUniform*().
    
    v2: Set driver-specified flag in NewDriverState when glUniform* is
        used to bind an image unit.
    v3: Abbreviate argument type check.

    glsl: Add image built-in function generator.
    
    Because of the combinatorial explosion of different image built-ins
    with different image dimensionalities and base data types, enumerating
    all the 242 possibilities would be annoying and a waste of .text
    space.  Instead use a special path in the built-in builder that loops
    over all the known image types.
    
    v2: Generate built-ins on GLSL version 4.20 too.  Rename
        '_has_float_data_type' to '_supports_float_data_type'.  Avoid
        duplicating enumeration of image built-ins in create_intrinsics()
        and create_builtins().
    v3: Use a more orthodox approach for passing image built-in generator
        parameters.
    v4: Cosmetic changes.

    glsl/ast: Generalize some sampler variable restrictions to all opaque types.
    
    No opaque types may be statically initialized in the shader, all
    opaque variables must be declared uniform or be part of an "in"
    function parameter declaration, no opaque types may be used as the
    return type of a function.
    
    v2: Add explicit check for opaque types in interface blocks.  Check
        for opaque types in ir_dereference::is_lvalue().

    glsl/ast: Forbid declaration of image variables in structures and uniform blocks.
    
    Aggregating images inside uniform blocks is explicitly disallowed by
    the standard, aggregating them inside structures is not (as of GL
    4.4), but there is a similar problem as with atomic counters: image
    uniform declarations require either a "writeonly" memory qualifier or
    an explicit format qualifier, which are explicitly forbidden in
    structure member declarations.  In the resolution of Khronos bug
    #10903 the same wording applied to atomic counters was decided to mean
    that they're not allowed inside structures -- Rejecting image member
    declarations within structures seems the most reasonable option for
    now.
