141905f9fd Consume whitespace before, rather than after, reading a token 
Simplifies several things

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.

33307e789a Update tools/generate-identifier-regex.js 
So that it can also spit out the astral maps.

d76ea4b3be Make the tokenizer aware of multi-byte characters in ES6 mode 
Add a data structure to recognize astral identifier chars. Parse whole
code points when looking for identifiers.

891d5d07dd Allow braced \u escapes in identifiers 
We still can't properly recognize code points as ES6-style
identifier chars.

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).

6dee98d1b9 Adapt ES6 template handling to new tokenizer. 
Avoid need for:
* extra `templates` array in favor of new `tokContext`;
* special location handling for first & last template elements;
* separate `_templateContinued` token in favor of same `_template`.

Adds:
* token types for backQuote and dollarBraceL instead of skipping them
so they can be handled (i.e. highlighted differently).

e7beee177d Remove deprecated ComprehensionBlock.of property. 
Comprehensions were moved to ES7 anyway, so there is no sense
in keeping intermediate no-more-supported syntax.
