Truffle: Revert: fix compilation issue; after a method is compiled (but not yet installed), it still needs to call the already compiled children.
Add a getter method to that returns the HotSpot VM symbol string associated via HotSpotVMField annotation. Renamed a similar existing method that returns  HotSpot VM symbol string associated via HotSpotVMValue annotation.
Instrumentation: Removed extends SyntaxTagged from Wrapper interface.
SL/Instrumentation: Removed unnecessary methods related to above change.
