RFR: 8299795: Relativize locals in interpreter frames [v2]

[Fredrik Bredberg]

> Implementation of relativized locals in interpreter frames for x86. x64, arm, aarch64, ppc64le and riscv.
> Not relativized locals on zero and s390 but done some changes to cope with the changed generic code.
> Tested tier1-tier8 on supported platforms. The rest was sanity tested using Qemu, except s390, which was only tested by GitHub Actions.
