Remove unnecessary state restoring logic from analyzer constraint generation. The `TypeConstraintGatherer` methods `trySubtypeMatch`, `_functionType`, `_functionType0`, and `_recordType` have the convention that if they do not find a match, they leave the set of gathered constraints in the same state it was in at the time of the call. The shared methods they invoke (`performSubtypeConstraintGenerationForFutureOr`, `performSubtypeConstraintGenerationForTypeDeclarationTypes`, and `performSubtypeConstraintGenerationForFunctionTypes`) all follow the same convention. Because of this convention, much of the logic in `trySubtypeMatch` for restoring the state of gathered constraints was actually redundant; this CL removes the redundant logic. It also adds some comments to try to clarify the calling conventions.

Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
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.
See LICENSE and PATENT_GRANT.
