Aske Simon Christensen aa85b09931 Remove broken generic supertype optimization.
The class hierarchy analysis maintains, for each class, a map from raw
supertypes to actual, parameterized supertypes. As an optimization, it
can share these maps between a class and one of its subclasses.

However, the sharing/copying mechanism sometimes ends up with entries
in the map that should not have been there.

This commit removes the optimization and always uses a separate map
for each class.

Closes https://github.com/dart-lang/sdk/issues/31996
