This fixes the regression introduced by [JDK-8329665](https://bugs.openjdk.org/browse/JDK-8329665), which added `ResourceMark` in `frame::oops_interpreted_do`. This is not really correct, as closures we call with that method can do resource allocations. The patch avoids this problem by cleanly allocating on C heap.
The mainline patch wants `has_valid_mask` infrastructure added as part of [JDK-8315954](https://bugs.openjdk.org/browse/JDK-8315954). That patch has implications for Graal, and have unresolved bug tail. Therefore, I just picked up relevant infra hunks here.
Additional testing:

- [ ] Linux AArch64 server fastedebug, `all`
