JDK-8200303 - C2 should leverage profiling for lookupswitch/tableswitch
Description
Current output:

     7      UnknownNode<0x00007fe79787c428> ===  9  8    [[ 6  28 ]]
     28     IfFalse ===  7  [[ 27 ]]

7 is a MachIf. The SA has a MachIfNode that can display profile data but it's not used here. 

Once JDK-8200303 is pushed a MachJumpNode will need to be implemented too.
