This change moves the transformers for ES2015, CommonJS, AMD, UMD, and System to the end of the transformation chain. In addition this cleans up the various module transformers to be more consistent.
This will allow us to isolate emit helpers to specific transformations, which was blocked by the fact that the module transformation happened very early in the transformation chain.
This also fixes a compiler crash when emitting a destructuring assignment with a destructuring target of an exported variable with
--module system
.Fixes #11770
