Paul Berry c8587ce199 Flow analysis: don't use == to compare types. 
Includes an integration test illustrating where this would have caused
incorrect behavior (due to the fact that the analyzer's `DartType.==`
doesn't yet distinguish nullabilities - see #37587), as well as unit
tests that will ensure we don't regress even after #37587 is fixed.

Paul Berry 7b6c667863 Flow analysis: rework tracking of nullability. 
We now track nullability via type promotion, e.g. by promoting from
`int?` to `int` to represent a non-nullable value.

I've added a few more unit tests of flow analysis that were helpful
while preparing this CL.  I plan to add more tests in follow-up CLs.

A few behaviors are lost by this change:

- We no longer track whether a variable's value is exactly null
  (previously the tests annotated such variables as "nullable", which
  was a bit misleading).  I'm not sure whether we really want this
  feature or not; I've filed
  https://github.com/dart-lang/language/issues/461 for discussion.

- Assignment of a non-null value to a nullable-typed variable no
  longer promotes it to non-nullable.  I think we want to get this
  behavior back, but we'll need to add a little bit more machinery to
  get it back (we need to allow assignments in general to promote.
  I'll address in follow-up CLs.  See
  https://github.com/dart-lang/language/issues/440 for discussion.

- A promotion to non-nullable that happens during a "try" block is
  lost if there is a "finally" block.  I think we want to get this
  behavior back, but we'll need to add a little bit more machinery to
  do so, to allow promotions in general to be preserved by
  try/finally.  I'll address in follow-up CLs.

Paul Berry 0c6b3d1277 Migration: do better function type formatting in DecoratedType.toString. 
We now wrap named argument types in `{}` and optional positional
argument types in `[]`.

A few unit tests have been added to verify this functionality; I
didn't exhaustively test the implementation of DecoratedType though.
