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
