    vcc: make vgc probes actual pointers to compound literals
    
    This is one of the cases where arrays do not behave like pointers, but besides
    the slightly more elaborate syntax I think a compound literal is what we
    intended all along, just using the array syntax as a convenience.
    
    Fixes #4410
    
    Ref #4418
