fc8314e810 minor fix for dropping unused definitions. 
function f(x, y) {
        var g = function() { return h() };
        var h = function() { return g() };
        return x + y;
    }

now compresses to `function f(x, y) { return x + y }`

6f45928a73 add fromString argument to UglifyJS.minify (allows to pass the source 
code, instead of file names, as first argument).

a21f3c6cdd employ a better parser for command-line arguments 
to support passing commas in strings in for example:

    uglifyjs2 -cd TEST="'a,b'" <<EOF
    console.log(TEST);
    EOF

    → console.log("a,b")

8f66458598 the sort option is broken anyway, removed it 
we need to mangle names from outermost to innermost scope; mangling names
from inner scopes before we got to the outer scope won't work correctly,
therefore sorting doesn't make sense.

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 :-\

1b6f8d463f remove the $self hack

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
