Stephen Adams 7fd4f25b62 [dart2js] Add generated JavaScript to --dump-ssa output. 
At the end of codegen, 'trace' the generated JavaScript to the `.cfg`
file, and 'trace' the JavaScript after the generator rewrite when this
happens.  This gives an easy way to see the non-final JavaScript from
before the transform. The 'trace' of the JavaScript is a little bit of
an abuse of the `.cfg` file format, but it is convenient to see the
SSA CFG and JavaScript with the same tool.

For this to work, js_ast printing needs to work for pre-finalized
ASTs. Most of this change is implementing `isFinalized` for every AST
node, and printing something indicative of the non-finalized nodes. For
example, unfinalized holders are printed as `Holder"<something>"`.
