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.

774f2ded94 minor optimization 
for `==` or `!=` against a constant, prefer to display the constant first.
should help a bit after gzip, i.e.:

    typeof foo=="undefined"
    ^^^^^^    ^^^^^^^^^^^^^

vs:

    "undefined"==typeof foo
    ^^^^^^^^^^^^^^^^^^^     (longer sequence that could repeat)

idea stolen from closure.

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 }`

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 :-\
