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)

66c869c8f6 switch branches must be declared required so that the compressor doesn't
replace nodes with a single statement.

looks stable for now, though mess begins to sink in.  need to review the AST
hierarchy.

7fcb6bcb12 fix code generator for this case:
if (foo) {
  with (bar)
    if (baz)
      x();
} else y();

(the compressor removes the brackets since the consequent consists of a
single statement, but the codegen must include the brackets because
otherwise the `else` would refer to the inner `if`)

f53e139d3c fix output for certain edge cases
the statements if, for, do, while and with might have an AST_EmptyStatement
as body; if that's the case, we need to make sure that the semicolon gets in
the output.

7ae1c600a2 some reorganization
(moved pretty much everything that relates to scope in scope.js, added a
module for NodeJS that can be used with require() and exports everything.)

99456c6156 more fixes:
- added walker for AST_ObjectProperty
- handle redefinitions properly (only mangle one symbol, make them all point
  to a single definition)

DynarchLIB seems to run fine after mangling + compressed output.

ef87c9fd8f big speed improvement (observable when beautify = false)
who would have thought that str.charAt(str.length - 1) is not a constant,
instant operation?  seems to get slower and slower as the string grows.

0.6s vs. 3s
