perf perf_regs: Switch from arch string to int e_machine

The arch string requires multiple strcmp to identify things like the
IP and SP.

Switch to passing in an e_machine that in the bulk of cases is computed
using a current thread load.

The e_machine also allows identification of 32-bit vs 64-bit processes.
