Don't mix strings with directives in output 
* Don't interpret strings with escaped content as directive
 * Don't interpret strings after empty statement as directive
 * Adapt output to prevent strings being represent as directive
 * Introduce UGLIFY_DEBUG to allow internal testing like EXPECT_DIRECTIVE

dcfc514c38 Improve yield support and restrict usage of strict 
- 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

Special thanks to @rvanvelzen and @kzc for reviewing this patch and
providing constructive feedback over and over again.

634f231b78 First class block scope 
- Make let, const, and class symbols be declared in a block scope.
- Piggy back on existing catch symbol implementation to get block-aware mangling working
- Make sure unused block-scoped declarations can be dropped
- Don't eliminate a block if it has a block-scoped declaration
- Remove silly empty anonymous blocks left over from drop_unused
- AST_Toplevel now gets to call drop_unused too, since block-scoped variables aren't global!
- Don't consider block declarations global

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.

ae07714927 Add filename to the JS_Parse_Error exception. 
It would be nice to have access to the filename of the file that includes the code that causes a JavaScript error. This is especially handy if uglifying multiple files at once.

Only a small change is needed for this to happen as it's already available in the function that throws the error.

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.

bb0a762d12 Only allow identifier start characters at the beginning of identifiers. 
Without this fix, the following source:

   x = {"\u200c": 42};

would incorrectly be converted into a quoteless key. But while \u200c is allowed
to be in identifiers, it cannot be at the beginning, as per ES5.

(For example, the SockJS client library doesn't work under uglify starting with
d9ad3c7c.)

b14d3df3d2 Keep legit code working even when --screw-ie is not passed. 
Previously:

    Without `--screw-ie`, UglifyJS would always leak names of function
    expressions into the containing scope, as if they were function
    declarations.  That was to emulate IE<9 behavior.  Code relying on this
    IE bug would continue to work properly after mangling, although it would
    only work in IE (since other engines don't share the bug).  Sometimes
    this broke legitimage code (see #153 and #155).

    With `--screw-ie` the names would not be leaked into the current scope,
    working properly in legit cases; but still it broke legit code when
    running in IE<9 (see #24).

Currently:

    Regardless of the `--screw-ie` setting, the names will not be leaked.
    Code relying on the IE bug will not work properly after mangling.
    <evil laughter here>

    Without `--screw-ie`: a hack has been added to the mangler to avoid
    using the same name for a function expression and some other variable in
    the same scope.  This keeps legit code working, at the (negligible,
    indeed) cost of one more identifier.

    With `--screw-ie` you allow the mangler to name function expressions
    with the same identifier as another variable in scope.  After mangling
    code might break in IE<9.

Oh man, the commit message is longer than the patch.

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.

5276a4a873 add AST_Accessor and AST_SymbolAccessor node types 
AST_Accessor will represent the function for a setter or getter.  Since they
are not mangleable, and they should not introduce a name in scope, we have a
new node for their name (AST_SymbolAccessor) which doesn't inherit from
AST_SymbolDeclaration.

fc39553714 use AST_Lambda for object setters/getters 
so that the optimization that drops the name if unused doesn't apply.

f4584af42c using makeComparator from acorn to generate functions that tests whether a 
string is keyword, reserved etc.

speeds up the parser a bit, though not spectacular.. still far from acorn.

924aa58060 more optimizations that v1 does and some cleanups 
- a = a + x ==> a+=x
- joining consecutive var statements (hoisting is not always desirable)
- x == false ==> x == 0, x != true ==> x != 1
- x, x ==> x; x = exp(), x ==> x = exp()
- discarding useless break-s

8633b0073f cleaned up usage of AST_BlockStatement 
The following nodes were instances of AST_BlockStatement: AST_Scope,
AST_SwitchBlock, AST_SwitchBranch.  Also, AST_Try, AST_Catch, AST_Finally
were having a body instanceof AST_BlockStatement.

Overloading the meaning of AST_BlockStatement this way turned out to be a
mess; we now have an AST_Block class that is the base class for things
having a block of statements (might or might not be bracketed).  The
`this.body` of AST_Scope, AST_Try, AST_Catch, AST_Finally is now an array of
statements (as they inherit from AST_Block).

Avoiding calling superclass's _walk function in walkers (turns out we walked
a node multiple times).

d7c1dc6c05 a LabeledStatement should be in fact a StatementWithBody 
This fixes output for:

    if (foo) {
        moo: if (bar) {
            break moo;
        }
    } else {
        baz();
    }

(the labeled statement must be outputted inside brackets)
