[PATCH v2 0/3] Support register names of all architectures

The following changeset applies some corrections to the way system
registers are processed and presented when reading perf.data files using
the various perf tools.
The commit message from [3/3] shows how register names aren't correctly
presented when performing x-arch analysis of perf.data files (recording
in one arch, then reading the file from a different arch).
- [PATCH 1/3] Fixes a potential out-of-bounds access when reading the
values of the registers in the perf.data file.
- [PATCH 2/3] Fixes an issue of ARM and ARM64 registers having the
same enum name.
- [PATCH 3/3] Refactors the function "perf_reg_name" declared in the
"tools/perf/util/perf_regs.h" header, in order to support every arch.
Thanks,
German

Changes since v1
- Added "Reported-by" tags.
- Removed [PATCH 2/4] because it's not needed (suggested by Athira
Rajeev).
- Removed [PATCH 3/4] which created additional header files with the
register names of every arch.
- Introduced [PATCH 2/3] to deal with ARM and ARM64 registers having the
same enum name across "/tools/perf/".
- Reworked the refactor of "perf_reg_name" function (now implemented in
perf_regs.c, rather than in the header file) in [PATCH 3/3].
