8459481e65 Represent a tokenizer as an instance of the parser 
This completely changes the interface, and removes most of the complexity
in the old tokenizer interface (jump-to-position was removed, since it is
all kinds of unreliable given the new tokenizer context system).

bc48c02a18 Move the parser state into an object 
Makes almost everything in acorn.js a method of this object.

Performance is not significantly affected on a modern V8. Makes the
code reentrant and allows us to more easily expose more methods
externally in the future.

On the other hand, the proliferation of `this.` is unfortunate.

cdd444eff1 Speed-up reading words, strings and templates. 
Now identifiers and strings even with escaped chars are read
in optimized way by reading entire chunks delimited by escape
chars (and not bailing to deopt mode on first one).
