German Gomez cd6382d827 perf test arm64: Test unwinding using fame-pointer (fp) mode 
Add a shell script to check that the call-graphs generated using frame
pointers (--call-graph fp) are complete and not missing leaf functions:

  | $ perf test 88 -v
  |  88: Check Arm64 callgraphs are complete in fp mode                  :
  | --- start ---
  | test child forked, pid 8734
  |  + Compiling test program (/tmp/test_program.Cz3yL)...
  |  + Recording (PID=8749)...
  |  + Stopping perf-record...
  | test_program.Cz
  |                  728 leaf
  |                  753 parent
  |                  76c main
  | test child finished with 0
  | ---- end ----
  | Check Arm SPE callgraphs are complete in fp mode: Ok

It's supposed to work with both unwinders:

  | $ make                # for libunwind (default)
  | $ make NO_LIBUNWIND=1 # for libdw

Tester notes:

Ran it on N1SDP and it passes, and it fails if b9f6fbb3b2 ("perf
arm64: Inject missing frames when using 'perf record --call-graph=fp'")
isn't applied.

Fixes: b9f6fbb3b2 ("perf arm64: Inject missing frames when using 'perf record --call-graph=fp'")
