Correct 4 static type expectations in test Work on https://github.com/dart-lang/sdk/issues/54002 revealed that the test least_upper_bound_greatest_closure_1_test.dart contains 4 static type expectations that are incorrect according to the definition of `UP` and this CL corrects those expectations. The updates associated with 54002 will change the behavior of the cfe and the analyzer such that they have the correct expectations (they currently succeed with the incorrect static type expectations, that is, they need to be updated in order to compute `UP` correctly, but that will occur as part of the update described in 54002, so we will approve the test failures caused by this CL and refer to 54002).

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.
