[PATCH v6 0/7] perf: Cross arch annotate + few miscellaneous fixes

[Ravi Bangoria]

Currently Perf annotate support code navigation (branches and calls)
only when run on the same architecture where perf.data was recorded.
But, for example, record on powerpc server and annotate on client's
x86 desktop is not supported.

This patchset enables cross arch annotate. Currently I've used x86
and arm instructions which are already available and added support
for powerpc.

Additionally this patch series also contains few other related fixes.

Patches are prepared on top of acme/perf/core and tested it with x86
and powerpc only.

Note for arm:
I don't have arm test machine. As suggested by Russell in one of the
review comment, I've copied all instructions from default table to
arm table. This way it want break tool on arm but cleanup is needed
for x86 specific instructions added in arm table.

Example:

  Record on powerpc:
  $ ./perf record -a

  Report -> Annotate on x86:
  $ ./perf report -i perf.data.powerpc --vmlinux vmlinux.powerpc

Changes in v6:
  - Instead of adding only those instructions defined in #ifdef __arm__,
    add all instructions from default table to arm table.
