Subject: perf tools: Add interface to arch registers sets

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).
