Log Message:
-----------
[dart2wasm] Enable --gufa also in deferred loading scenario

This gives around -0.3% in compressed/uncompressed of e main module.

The GUFA pass in binaryen no longer requires closed world assumptions.
So we can enable it in the deferred loading case where we currently
optimize individual modules independently.

See discussion in [0].
