    Remove some unimplemented GranSim primops
    
    Summary:
    An attempt to use these resulted in an error like:
    
    [1 of 1] Compiling Main             ( p.hs, p.o )
    ghc: panic! (the 'impossible' happened)
      (GHC version 7.8.4 for x86_64-unknown-linux):
    	emitPrimOp: can't translate PrimOp  parAt#{v}
    
    Test Plan: validate

 These primops are pretty weird.
