[Patch v6 0/4] Perf tools: Support eGPRs/SSP/SIMD registers sampling

[Dapeng Mi <dapeng1.mi@linux.intel.com>]

This patch-set adds sampling support for x86 eGPRs/SSP/SIMD registers in
perf tools base on the corresponding sampling support for eGPRs/SSP/SIMD
registers in kernel[1]. In previous version, these perf-tools patches
are integrated as a whole patch-set with the kernel patches, but it's
split and posted to an independent perf-tools patch-set for convenient
review.

Changes since v5:
- Split the sampling support for eGPRs/SSP registers and SIMD registers
  into 2 patches.
- Address Ian's comments including,
  * Convert the architecture dependent functions into regular
    architectural independent functions, like whatperf_reg_name() does.
  * Refine the functions name to represent what the functions really do.
  * Add comments for some key functions arguments.
  * Misc enhancements.
