Daco Harkes 40bbb6dcc2 [vm] Const map, remove invalid assert 
Isolates are allowed to race each other to initialize _indexNullable,
the last isolate wins. See
https://dart-review.googlesource.com/c/sdk/+/210726 and
https://dart-review.googlesource.com/c/sdk/+/203765.

These asserts were wrong, because another isolate could have initialized
_indexNullable in between places calling _createIndex and _createIndex
itself.

Closes: https://github.com/dart-lang/sdk/issues/47118

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).
