When the .packages file has changed we need to re-check all package-uris
to see if we need to invalidate the builders (if the file uri for a
package uri library (e.g. if the package was upgrade) has changed we
have to invalidate it).
This translation is semi-expensive though, so if we can avoid it that
would be a good thing.
This CL caches the "base URI" for packages from the previous run,
so we can start by comparing the base-URIs: If the base-uri for a
specific package hasn't changed, nor will the actual translation.
Only if the base uri has changed we do the actual translation,
and thus save many package-to-file-uri translations.
An internal benchmark via kernel worker of lots of outline
calculations in worker mode with reuse and the incremental compiler
(where the .packages file change every time and we have lots of
package-uri libraries) goes from ~185 seconds to ~162 seconds.

Before this CL we removed from from the builders map, but left them in
the libraries list.
When using the incremental compiler via kernel worker (where we
continually replace dill builders) that meant that this list would just
keep growing.
This CL cleans it up and the builders map and the list should now be
in sync

During outline building the token stream was split after every field
initializer needed for top-level type inference. Since the token
stream is a doubly-linked list it's also necessary to split the token
stream before the field initializer in order to possibly collect the
unnecessary tokens.

These builders have some unused generality: they have an unnecessary
type parameter and the implementation classes have unused fields. As
currently used, they could be replaced with an int but the class is
kept in anticipation of adding behavior (compiling annotations).

This CL revises the scanner API so that tokens are always prepended
to the beginning of the token stream. This allows the parser handling
of error tokens to be simplified. Any clients using the scanner directly
rather than through the scanner API should call scannerRecovery
if the scanner has detected errors in the content.

This is the first of several CLs that move error tokens to the head
of the token stream so that parser handling of error tokens
can be simplified and less error prone.
In this particular CL:
- update parser to handle error tokens at the head of the token stream
- remove several places that analyzer was preprocessing error tokens
now that the parser handles them

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.

As expressions and instantiations lose the connection to the current type environment when put into an unevaluated constant expression. This leaves type variables unsubstituted when the expressions are lazily evaluated leading to invalid compile-time errors. This is avoided by substituting the type variable when creating the unevaluated constant. If the type variables are not substituted by concrete types, this is flagged as a valid compile-time error during the lazy evaluation.
