41c627379c Reverting "added option for dropping unused params" 
Revert "added option for dropping unused params"

(turns out we already had the `unused` option for this.)

This reverts commit e54df2226f.

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,,].

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.

851b48e4a3 fix compressing benchmark.js (it tried to evaluate a statement) 
the following code in benchmark.js triggered the issue:

    support.decompilation = Function(
      'return (' + (function(x) { return { 'x': '' + (1 + x) + '', 'y': 0 }; }) + ')'
    )()(0).x === '1';

technically that could be resolved into a constant expression, but seems
it's being used here for browser bugs detection :-\

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.

f26f3b44bc small improvements in wrap_commonjs: 
- use MAP.splice instead of a BlockStatement to inject code (avoids some
  warnings in the linter)
- use the original symbol in exports, so that we get the proper source mapping

2bd8a118c2 define AST_Node.from_mozilla_ast(ast) 
returns an UglifyJS2 AST given a Mozilla AST.  Still needs some work to do
(need to create specific nodes like AST_SymbolRef, AST_SymbolLambda
etc. instead of base AST_Symbol, in order for the mangler/compressor to work
properly)
