I would like author of this code to review this. @theRealAph please look.

There is difference between x64 and aarch64 how this stub is generated. For x64 it is generated as part of compiler stubs under `#ifdef COMPILER2`. For aarch64 it is in final stubs. Why is difference?

If it is really C2 specific stub then why `UseSecondarySupersTable` flag is global?

`MacroAssembler::lookup_secondary_supers_table*()` methods could be also in `c2_MacroAssembler*` files.
