[ignition] Move destructuring assignments to bytecode generation

Browse Source 
Instead of de-sugaring destructuring assignment in the parser (using the
pattern rewriter), pass the Object/ArrayLiterals through to the bytecode
generator, which can desugar them in-place.

This allows us to decrease the amount of AST node creation, and improve
the generated bytecode using domain-specific knowledge. As a side effect
we partially fix an old execution ordering spec bug.

Currently only implemented for assignments, not declarations, as the
latter has some additional complexity.
