`/bin/sh -c` trick wasn't working for several reasons:

* `/bin/sh -c "..."` expects the first argument after `"..."` to be a
  `$0`, not a `$1`. Previously `-n` wasn't passed to `nm` because of
  this, and many symbols were ordered improperly
* `c++filt` was applied not only to the names of the functions but to
  their `nm` prefixes like `t` and `a` (`t xxx` turns into
  `unsigned char xxx`).

Instead of applying `c++filt` wide and using `sh -c`, execute `nm` as
requested by `deps/v8/tools/tickprocessor.js` and apply `c++filt` to all
matching entries manually.

Included test demonstrates where previous approach failed: all builtins
were merged into `v8::internal::Builtins::~Builtins`, because they were
prefixed by `t` in `nm` output.

* Separates the basic usage and the benchmarking into different tests

* Moves the timing-sensitive benchmark function into a separate module,
and reparses the module on every iteration of the loop to avoid shared
state between timing measurements.
