Merge #4065 
4065: Complete unqualified enum names in patterns and expressions r=matklad a=nathanwhit

This PR implements the completion described in #4014.
The result looks like so for patterns:

and for `expr`s:

I'm not confident that the completion text itself is very robust, as it will unconditionally add completions for enum variants with the form `Enum::Variant`. This means (I believe) it would still suggest `Enum::Variant` even if the local name is changed i.e. `use Enum as Foo` or the variants are brought into scope such as through `use Enum::*`.
