    pipeline: remove dubious optimization
    
    This removes an optimization that I added at some point, which I'm
    pretty certain I only added on a hunch. Reading the description I'm not
    really convinced it makes sense to do this given that the fixed vertend
    and fragend are currently listed before the glsl vertend and fragend in
    the order that we look for a suitable backend. This means unless the
    pipeline depends on glsl (e.g. due to an associated snippet) we would
    reselect the fixed backend anyway, and if it really did depend on glsl
    then we'd notice when we come to flush and switch backends there any way.
