[vm]: Rewrite library_filters in source_report

When library_filters were given, we used to prefill the script_table_,
then just assume that any scripts not in the script_table_ must have
been filtered out. We wrote it this way to avoid checking the filters
in every GetScriptIndex call. But in some cases (eg mixins),
lib.LoadedScripts() can miss some scripts, so they'd be incorrectly
omitted from the table.

The new implementation lazy loads the scripts, the same way it works
when there are no library_filters. Skipped scripts are still placed in
the script_table_, but given an index of -1, and omitted from
script_table_entries_.

Change-Id: Ide938ddfa9a3750c72c615e296b1a23875e46ab8
TEST=CI (also manually tested that the bug is fixed, but it's a really fiddly setup and I'm not sure how to put it in a unit test. See bug for details)

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
