    glsl: cross validate varyings with a component qualifier

    This change checks for component overlap, including handling overlap of
    locations and components by doubles. Previously there was no validation
    for assigning explicit locations to a location used by the second half
    of a double.

    V3: simplify handling of doubles and fix double component aliasing
    detection

    V2: fix component matching for matricies
