target/ppc: Implement ppc_cpu_record_sigsegv
Record DAR, DSISR, and exception_index. That last means
that we must exit to cpu_loop ourselves, instead of letting
exception_index being overwritten.
This is exactly what the user-mode ppc_cpu_tlb_fill does,
so simply rename it as ppc_cpu_record_sigsegv.
