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

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.

7691bebea5 Rework has_directive 
It's now available during tree walking, i.e. walker.has_directive("use
asm"), rather than as part of the scope.  It's thus no longer necessary
to call `figure_out_scope` before codegen.  Added special bits in the
code generator to overcome the fact that it doesn't inherit from
TreeWalker.

fbbaa42ee5 Add option to preserve/enforce string quote style 
`-q 0` (default) use single or double quotes such as to minimize the number of
 bytes (prefers double quotes when both will do); this is the previous
 behavior.

`-q 1` -- always use single quotes

`-q 2` -- always use double quotes

`-q 3` or just `-q` -- always use the original quotes.

Related codegen option: `quote_style`.

Close #495
Close #460

Some `yargs` guru please tell me why `uglifyjs --help` doesn't display the
help string for `-q` / `--quotes`, and why it doesn't output the expected
argument types anymore, like good old `optimist` did.

24bc09b79b Fix #556 
`\uFEFF` (ZERO WIDTH NO-BREAK SPACE) is removed when parsing, but was
un-escaped for the output when `ascii_only` was false.

When using
UglifyJS multiple times (creating packages from minified sources, for
example), this would lead to problems because the byte was removed when
parsing for the second time.

c75f5a1fd8 Fix #597 
NaN and Infinity were replaced in the output generation, instead of
during compression. This could lead to results where `1/0` was inserted
without parens leading to invalid output.

The nodes are replaced in the compression step now, and the output
generation returns their regular names. This should not be a problem,
since they're already only constructed from the original name.

39d8880f2c Fix max_line_len not working for JSON files 
As `maybe_newline()` is only called when `might_need_semicolon` is `true`, the `max_line_len` option has no effect for files without (or with very few) semicolons (like JSON files). A simple for this problem is to use `maybe_newline()` instead of `noop` as the `newline()` function in non-beautify mode.

c5ed2292bf Fix parsing setters/getters (allow keywords for name). 
The "key" property was always "set" or "get", which didn't make much sense.
Now it'll be the actual name of the setter/getter (AST_Node), and the
AST_Accessor object itself, which represents the function, won't store any
name.

b1febde3e9 Fix output for arrays whose last element is a hole: [1,,] 
1529ab96 started to do this (by considering holes to be separate from
"undefined") but it still converted
   [1,,]    (length 2, last element hole, trailing comma)
to
   [1,]     (length 1, trailing comma)

Unfortunately the test suite doesn't really make this clear: the new test here
passes with or without this patch because run-tests.js beautifys the expected
output (in "make_code"), which does the incorrect transformation! If you make
some manual change to arrays.js to make the test fail and see the INPUT and
OUTPUT, then you can see that without this fix, [1,,] -> [1,], and with this fix
it stays [1,,].

1529ab965a Fix output for arrays containing undefined values. 
1b6bcca7 was a first attempt at this. That commit made Uglify stop replacing
holes with undefined, but instead it started replacing undefined with
holes. This is slightly problematic, because there is a difference between a
hole and an undefined value. More problematically, it changed [1,undefined] to
[1,] which generally doesn't even parse as a hole (just as a trailing comma), so
it didn't even preserve the length of the array!

Instead, parse holes as their own special AST node which prints invisibly.
