We need to add wrapper methods and other methods to the vmIntrinsics enumeration, without committing to implementing them as compiler intrinsics.  This requires a new categorization (compiler-supported vs. other).

Also, the lazy evaluation scheme used by methodOop::intrinsic_id is obsolete and should now be removed.
