Changes the analyzer code that reports the following errors to use the
literate diagnostic reporting API:
- `undefinedEnumConstant`.
- `undefinedGetter`.
In the process I've cleaned up the type of the second argument (now
called `type`). Previously, some call sites passed in a type and
others passed in a string; now all call sites pass in a type.
