Add front-end test for set/map literal disambiguation.
The test exposes three problems:
- The disambiguation criterion in the type inference is incorrect, as
it infers a map when the context is a LinkedHashSet. This will be
fixed in an upcoming CL.
- Assigning a map literal to a LinkedHashMap produces a static error
("isn't of expected type") due to exact types. Rules for exact types
are currently unspecified, and the language team has expressed some
interest in allowing this case. See also
https://github.com/dart-lang/sdk/issues/33307
- Type arguments for the map literal are not inferred from the context
when the outer context type is a LinkedHashMap. This is consistent
between the CFE and analyzer. If the LinkedHashMap case is to be
supported, this must be fixed as well.
