Store type inference errors into EntityRef.

Store type inference errors into EntityRef.

The errors will be associated with inference targets - top-level
variables, static class fields, instance class fields, overriding
instance method parameters with conflicting type in overridden members,
etc.

These errors will be accessible through corresponding Element(s) and
reported by LibraryAnalyzer, and so AnalysisDriver to the client. So,
we will not need to compute these errors once again in ErrorVerifier.
