> Remove special cases in `nmethod::is_deopt_entry` and `nmethod::is_deopt_mh_entry`. Graal used to generate a different code pattern from C2 for deopt handlers. This was changed in https://github.com/oracle/graal/commit/099f57b58edb23ed2184c11badea24edf36f30d2 to align Graal's code generation with C2. The special cases are no longer needed.

@gergo- 
Your change (at version 8028476c2e28e2c168676209260fa68194f74cf1) is now ready to be sponsored by a Committer.
