cd17a9b1a7 perf test demangle-ocaml: Switch to using dso__demangle_sym() 
The use of the demangle-ocaml APIs means we don't detect if a different
demangler is used before the OCaml one for the case that matters to
perf.

d68f036508 perf test: Move each test suite struct to its test 
Rather than export test functions, export the test struct. Rename with a
suite__ prefix to avoid name collisions.

Committer notes:

Its '&suite__vectors_page', not '&suite__vectors_pages', noticed when
cross building to arm (32-bit).

292c5ed168 perf tools: Preserve identifier id in OCaml demangler 
Some OCaml developers reported that this bit of information is sometimes
useful for disambiguating functions for which the OCaml compiler assigns
the same name, e.g. nested or inlined functions.

cef7af25c9 perf tools: Add OCaml demangling 
Detect symbols generated by the OCaml compiler based on their prefix.

Demangle OCaml symbols, returning a newly allocated string (like the
existing Java demangling functionality).

Move a helper function (hex) from tests/code-reading.c to util/string.c

To test:

  echo 'Printf.printf "%d\n" (Random.int 42)' > test.ml
  perf record ocamlopt.opt test.ml
  perf report -d ocamlopt.opt
