sparc64: Implement perf_arch_fetch_caller_regs
We provide regs->tstate, regs->tpc, regs->tnpc and
regs->u_regs[UREG_FP].
regs->tstate is necessary for:
user_mode() (via perf_exclude_event())
perf_misc_flags() (via perf_prepare_sample())
regs->tpc is necessary for:
perf_instruction_pointer() (via perf_prepare_sample())
and regs->u_regs[UREG_FP] is necessary for:
perf_callchain() (via perf_prepare_sample())
The regs->tnpc value is provided just to be tidy.
