I think this comment should explain that super/this invocation is included because its arguments are restricted too.

Probably yes, I think our agreement last time is that local/anonymous classes' captures, including the "outer this", are synthetic.

this test along with EarlyAssigmentNoPreview 2 and 3 are failing. But the idea is to integrate this PR after the code for flexible constructor bodies have been merged into lworld, which should make these 3 tests pass

Before this fix only strict fields were readable in the prologue phase. The proposed fix should allow any instance fields of identity classes to be readable in the prologue phase. This implies changes in flow analysis as before we were only tracking final and strict fields. There is also some "cooperation" needed in the code to detect cases when reading a field is not allowed in the prologue phase. For example some methods in Resolve don't have all the needed information at the moment they are dealing with some ASTs and part of the processing needs to be done in Attr
