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.

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
