code points when looking for identifiers.

891d5d07dd Allow braced \u escapes in identifiers

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.
