These functions only want the GPRs returned for SRA. This is because the
signal handler needs this map to relation between x86 GPRs and AArch64
GPRs.
When we added AF and PF to the SRA array we accidentally started
returning two more GPRs to the frontend. This caused the signal
delegator to start corrupting the members after GPRs in FEX's CoreState.
Corrupting 16-bytes after the gregs[] array.
This included corrupting:
- es_idx, cs_idx, ss_idx, ds_idx, gs_idx, fs_idx, _pad[]
