1. syntax: improve parameter without type suggestions …

   This commit improves the suggestions provided when function parameters
   do not have types:
   
   - A new suggestion is added for arbitrary self types, which suggests
   adding `self: ` before the type.
   
   - Existing suggestions are now provided when a `<` is found where a `:`
   was expected (previously only `,` and `)` or trait items), this gives
   suggestions in the case where the unnamed parameter type is generic
   in a free function.
   
   - The suggestion that a type name be provided (e.g. `fn foo(HashMap<u32>)`
   -> `fn foo(HashMap: TypeName<u32>)`) will no longer occur when a `<` was
   found instead of `:`.
   
   - The ident will not be used for recovery when a `<` was found instead
   of `:`.
