Paul Berry d9f191575a [analzyer] Refactor analyzeAnalysisOptions into a class.
Replaces the top level function `analyzeAnalysisOptions`, which
contained 3 nested local functions, with a class
`AnalyzeAnalysisOptions`, where the nested local functions have been
changed into private methods.

All the variables in the top level function that were implicitly
write- or read-captured by the nested local functions have been
changed into class fields or explicit method parameters. This should
make the code a lot easier to follow.

In this CL, I've tried hard to preserve the existing functionality
exactly; besides converting local variables to fields and parameters,
I haven't really made any changes to the core logic beyond code
motion. In follow-up CLs, I plan to make some simplifications that are
less obviously semantics preserving (but should be easier to review
since they won't involve so much code motion). Once that is done I
hope to be able to migrate the error reporting in this class to use
the literate diagnostic API.

SDK development code analysis

dartanalyzer used to be the tool for statically analyzing dart code at the command line. However, this tool has been replaced with dart analyze for this purpose in current SDKs and will no longer be published on pub.

Do not depend on the command line interface or other semantics in this directory as it is now an internal tool for SDK development, used as the dart2analyzer "compiler" for tools/test.py in the SDK. It is configured as part of the test runner, here.

SDK development usage

For SDK development, run analysis from the test tool to validate analysis conclusions on language samples in the testing directory. From the root of the SDK:

tools/test.py --build --use-sdk -c dart2analyzer co19 language

This will build the Dart VM and compile dartanalyzer into a snapshot, then use that snapshot while analyzing those directories under testing/. Without --use-sdk, test.py will use the source code version of the analyzer instead of the compiled one, which can be useful for debugging.
