This CL fixes a number of issues:
* Semi-leaking old components when starting over
(i.e. when loading a new sdk)
* Setting new filesystem not really working because the old one was
cached in the ProcessedOptions
* Leaking old state because of an apparent VM bug (http://dartbug.com/36983)

Had to do a few changes to make this happen:
1. Restored some of the code removed in the transformer, making class
hierarchy optional.
2. Split the "compile" method in bazel_worker.dart into two, since we
need the intermediate Component object in one of the case.

TL;DR: Unbind canonical names doesn't do what you think it does and
probably shouldn't (ever) be used. This CL stops using it in a few places.
Longer version:
When loading a dill file it:
- First loads the table of canonical names. These have no references yet.
- When a canonical name is asked for its reference it creates one if it
doesn't yet have one.
- When loading, for instance, a library, it asks for the reference.
When unbinding a canonical name:
- It removes itself (the canonical name) from the reference
- It removes the reference in itself
- Note: Whatever has a pointer to the reference keeps it, and the
reference points to whatever node it already pointed to.
This also means, that if we have a dill file that's split in two and:
- Load #1
- Load #2
that works fine, but if we
- Load #1
- Unbind canonical names
- Binds canonical names
- Load #2
stuff is not bound correctly (and an error is thrown).
And - the cause of this bug:
- Load #1
- Load #2
everything is fine
- Unbind canonical names
- Binds canonical names
- Load #2'
stuff is not bound correctly --- references points to stuff loaded as #2,
not as #2'. On top of being weird, wrong and confusing it also caused wrong
things to be but into the class hierarchy which ultimatly caused the crash.
This CL fixes it by not calling unbind and force loading of dill files
(at specific call sites) to create new libraries
(and in the process overwriting references ".node").

Without this, if an error occurs during serialization you get this message:
```
Internal problem: Compiler cannot run without a compiler context.
```
Instead of the real error.

This allows dartdevc and the bazel worker to user

Use --reuse-compiler-result --use-incremental-compiler to run in this mode.

This includes a `--target` flag (that in the future we can use for other targets
too) and a flag to accept the libraries.json file (currently needed to properly

This flag was always true so we can remove it and specialize the
remaining code that used it. The only code that used it was in the
Dart VM's async transformation.
Specializing that code led to some unused fields in the async helper
class which were removed. This triggered me to look at core types
which seems to have a lot of unused stuff.

Similar to how dart2js keeps its own target in package compiler.
This allows VmTarget to use package vm specific transformations and metadata.
