Adding header files to access unified API for arch registers. util/perf_regs.h - global perf_reg declarations arch/x86/include/perf_regs.h - x86 arch specific Adding perf_reg_name function to obtain register name based on the reg ID value, and PERF_REGS_MASK macro with mask definition of all current arch registers (will be used in unwind patches).
