RFR: 8310264: In PhaseChaitin::Split defs and phis are leaked

Sat Jun 17 16:17:21 UTC 2023

Hi,

`defs` and `phis` are leaked as they are resource allocated but not protected by a `ResourceMark`. The intention might have been for these to also live in the `split_arena`.. This change is the most conservative one, however, and does fix the memory leak.

Please consider, thanks.

Johan
