[analyzer] ContextRootImpl.isAnalyzed already have the resource, don't get it again
When analyzing rwf-materials (562 contexts) with a filled cache this
CL removes something like ~1.6 million calls to "isDirectorySync" which -
I think - reads from the filesystem.
On Linux I get this change (on Windows I'm guessing the change is bigger
as the filesystem is often slower):
Before the fix:
111662 ms
112053 ms
112176 ms
With this fix:
102829 ms
100934 ms
100991 ms
Difference at 95.0% confidence
-10379 +/- 1780.48
-9.26997% +/- 1.59023%
(Student's t, pooled s = 785.532)
I.e. it makes it ~10 seconds or ~9% faster.

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).
Dart is free and open source.
