This debug code was added quite a while ago, constructed such that we
wouldn't have to ship this code to our users.
However, this is the sole place in the compiler project where the ts
namespace "escapes" the bundle. By moving this debug code into the
compiler itself, we no longer have any references to the ts namespace
itself for our bundles that don't export anything (tsc,
typingsInstaller). This lets bundlers tree shake the compiler, reducing
the size of our output by _5.7 MB_ (a ridiculous improvement for
_adding_ code).
This step converts as many explicit accesses as possible in favor of direct imports from the modules in which things were declared. This restores the code (as much as possible) back to how it looked originally before the explicitify step, e.g. instead of "ts.Node" and "ts.Symbol", we have just "Node" and "Symbol".
This step converts each file into an exported module by hoisting the namespace bodies into the global scope and transferring internal markers down onto declarations as needed.
The namespaces are reconstructed as "barrel"-style modules, which are identical to the old namespace objects in structure. These reconstructed namespaces are then imported in the newly module-ified files, making existing expressions like "ts." valid.
