It is not a huge improvement, because it does not add static safety,
for this we would need to distinguish between unresolved and resolved
expressions, as separate types.
But it is still an improvement.
1. We get to know the node that was not resolved.
Maybe not enough, in case if it was because of the enclosing
now that this node was not resolved. But still something.
2. We group this use case into one place.

Adds support for pretty printing verbose annotations.
Adds support for force updating annotation texts useful for applying
the pretty printing to valid annotations.

DartType.== implementations ignore nullability if the flag is not true.
TypeSystem APIs eliminate nullability from types before doing anything.
Internally analyzer continues using actual nullability for types.
Package nnbd_migration opted into NullSafetyUnderstandingFlag.

No change in functionality. Just changing the analyzer's
nullability_test.dart so that it generates the `nonNullable`
annotation for a promotion from type parameter `E` to `E&Object`.
This makes it consistent with the front end test runner behavior.

This moves the five test suites for flow analysis along with the
constants test suite.
Note that a few files have formatting errors. I'll fix those in a
follow-up CL.

These data structures are only used for testing (and are not even
created in normal production use). Add "ForTesting" to their names so
that we are less likely to use them by accident.
