Thank you for working on this cleanup, @fandreuz! The changes look good to me. I only have one nit.

I also kicked off testing on our side and will keep you posted on the results.

src/hotspot/share/opto/phaseX.cpp line 812:

Suggestion:

PhaseIterGVN::PhaseIterGVN() : _delay_transform(false),
                               _worklist(*C->igvn_worklist())

Nit: align with line above
