110a1ac885 Make distinction between * method and * operator
Also add quotes to properties when necessary,

identifier

0af42d1831 Template fixes
* Fixes #1147: template strings not obeying -b ascii_only true
* Allow evaluation of template expressions by adding optimizers and
  walkers
* Make sure tagged templates are never changed
* Remove template tokenizer in parser, add template tokenizer in
  tokenizer. It is using a brace counter to track brace position of
  templates
* Add tokens `template_head` and `template_substitution` but parsing
  tokens stays mostly the same
* Do not output strings anymore in AST_TemplateString, instead use
  AST_TemplateSegment
* Fix parsing tagged templates, allowing multiple templates behind
  as spec allows this

These changes don't influence tagged templates because raw content
may influence code execution, however they are safe to do in normal
templates:
* Allow basic string concatenation of templates where possible
* Allow custom character escape style similar to strings, except in
  tagged templates

Note that expressions are still compressed in tagged templates.

Optional things that may be improved later:
* Custom quote style for templates if it doesn't have expressions.
  Making it obey the quote_style option if this is the case.

02c638209e Enable --screw-ie8 by default.
catch identifier is mangled correctly for ES5 standards-compliant JS engines by default.

Unconditionally use the ie8 if/do-while workaround whether or not --screw-ie8 is enabled.

To support non-standard ie8 javascript use: uglifyjs --support-ie8

3a7d53f3cf Move OctalEscapeSequence to read_escape_char
This should simplify and improve implementation, make it easier to
implement template strings, and keep master a bit more in sync with
harmony.

Previous implementation wasn't broken, though the loop gave me the
impression it could read infinite numbers and annoyed me a bit. It was
also slightly unnecessary because the lookup involved only 3 characters.

e645ba84cf Respect quote style in object literals
The option added in fbbaa42ee5 wasn't
being respected inside object literals, so quoted property names would
still be stripped out with this option.

This is mostly a corner-case, but useful when the output is passed to
something like the Closure compiler, where quoted property names can be
used to prevent mangling.

- Partially reverting 91cdb93e57 and eaf3911c31 and reimplement
- Add generators support for objects and classes
- Only classes can have static methods so restrict use of it

providing constructive feedback over and over again.
