RFR: 8279947: Remove two redundant gvn.transform calls in Parse::do_one_bytecode()

[Jie Fu]

Hi all,

May I get reviews for this small change?

The patch removes two `gvn.transform` calls in `Parse::do_one_bytecode()` which I think they are redundant.
Or am I missing something?

Testing:
  - tier1~3 on Linux/x64, no regression

Thanks.
Best regards,
Jie
