Port CallSite methods to C++.

Port CallSite methods to C++.

The goal is to port all of error stack trace formatting to C++.
We will do this bottom up, by first porting helper functions.

Eventually, CallSite methods will only be used when a custom
error stack trace formatter is defined via Error.prepareStackTrace.

LGTM with nits.

File src/messages.h (right):

https://codereview.chromium.org/1060583008/diff/1/src/messages.h#newcode99
src/messages.h:99: int GetLineNumber(Isolate* isolate);
To prevent future confusion, let's add a comment stating that the result is
1-based.

nit: debugging leftover?

nit: while you're here, delete this too?
