Some partial libraries have been minified, which results in boolean literals
being converted to `!0` and `!1`. This commit ensures that the linker can
process these values.

The filename of the source-span is now added to the Babel location
when setting the source-map range in the `BabelAstHost`.
Note that the filename is only added if it is different to the main file
being processed. Otherwise Babel will generate two entries in its
generated source-map.

The types of directives and pipes that are used in a component's
template may be emitted into the partial declaration wrapped inside a
closure, which is needed when the type is declared later in the module.
This poses a problem for JIT compilation of partial declarations, as
this closure is indistinguishable from a class reference itself. To mark
the forward reference function as such, this commit changes the partial
declaration codegen to emit a `forwardRef` invocation wrapped around
the closure, which ensures that the closure is properly tagged as a
forward reference. This allows the forward reference to be treated as
such during JIT compilation.

This commit adds the basic building blocks for linking partial declarations.
In particular it provides a generic `FileLinker` class that delegates to
a set of (not yet implemented) `PartialLinker` classes.
The Babel plugin makes use of this `FileLinker` providing concrete classes
for `AstHost` and `AstFactory` that work with Babel AST. It can be created
with the following code:
```ts
const plugin = createEs2015LinkerPlugin({ /* options */ });
```
