Jens Johansen 021b4a0bc8 Always reuse dart: libraries in computeReusedLibraries 
We don't support invalidating `dart:` libraries, so there's no reason
to include such libraries in the computeReusedLibraries calculations:
They should aways be reused.

This CL does exactly that.

On 430 flutter tests, it changes the time it takes to execute
`computeReusedLibraries` by -15.7188% +/- 8.83679%
(-193.125 ms +/- 108.571 ms for all 430 tests) (at 95% confidence).

Said another way it reduces the average runtime for
computeReusedLibraries from ~2.8 ms to ~2.4 ms.

Front end for Dart

This package provides a low-level API for use by compiler back ends that wish to implement the Dart language. It is intended for eventual use by dev_compiler, dart2js, and the Dart VM. In addition, it will share implementation details with the analyzer package--this will be accomplished by having the analyzer package import (and re-export) parts of this package's private implementation.

End-users should use the [dartanalyzer][analyzercli] command-line tool to analyze their Dart code.

Integrators that want to write tools that analyze Dart code should use the [analyzer] package.

Note: The APIs in this package are in an early state; developers should be careful about depending on this package. In particular, there is no semver contract for release versions of this package. Please depend directly on individual versions.
