regis@google.com 81bcb1f18a Distinguish between malformed and malbounded types (fix issues 12552 and 12554).
Add test.
Update status files.

Explanation of change: A malbounded type argument should not be mapped to
dynamic, as is a malformed type argument.
This change also adds a bunch of TODOs related to the encounter of malbounded
types in unexpected places.
A follow-up change will address these TODOs, add more tests, and may simplify
code that is still handling malformed types where they cannot occur anymore
after the spec simplified their handling.
