Subject[PATCH 11/15] perf, tool: Add interface to arch registers sets
Date
Adding header files to access unified API for arch registers.

In addition adding a way to obtain register name based on the
API ID value.

Also adding PERF_REGS_MASK macro with mask definition of
all current arch registers (will be used in unwind patches).
