`node --prof foo.js` may not print the full profile log file, leaving
the last line broken (for example `tick,`. When that happens, `readline`
will be stuck in an infinite loop. This patch fixes it.
Also introduced `common.isCPPSymbolsNotMapped` to avoid duplicated code
on tick-processor tests.

After this commit, `process.versions.v8` will look like:
"6.0.287.53-node.0".
The goal is that everytime we apply a non-official patch to `deps/v8`,
we increment our own number instead of V8's patch level.
This number must be set back to 0 after major V8 updates.

`/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.

This change cleans up outstanding comments on #3032. It improves error
handling when no isolate file is provided and adds the --prof-process
flag to the node binary which executes the tick processor on the
provided isolate file.
