This series enhances tooling to support new operations:

   - Support for MTE tag since Arm SPE v1.3;
   - Support for Advanced SIMD extension and SVE operations;
   - Support memcpy, memset and GCS operations;
   - Support extended operations for atomic, Acquire/Release and
     Exclusive instructions.
   - Enhance the data source for associated info, like floating-point,
     conditional, data processing, etc.

This series is divided into three parts:

   Patches 01 ~ 06: Support raw dump for new operations;
   Patches 07 ~ 17: Export the operation info into records, so that the
                    information can be later consumed by samples.
   Patches 18 ~ 25: Set the operation info into sample's data source and
                    SIMD flag, and updated the document.

This patch series is tested on FVP for native parsing and x86_64 for
cross parsing.

Can I get some comments from ARM folks?  I think I can merge part 1 and
2 before changing the kernel interface.

Thanks,
Namhyung
