The LBRs are relatively cheap to keep enabled and provide some history
to OOPSen, also some CPUs are reported to keep them over soft-reset,
which allows us to use them to debug things like tripple faults.

Therefore introduce a boot option: lbr_debug=on, which always enable
the LBRs and will print the LBRs on CPU init and die().
