Fold deduced pattern parsing into the general pattern parsing. (#2649)

Browse Source 
Depends on #2646 

Right now, deduced parameter handling is very narrow to `self` support. This folds it into pattern handling, which should eventually be a superset of deduced parameter support, so this will avoid more duplication of logic.

Note, this subtly adds handling of multiple deduced parameters, but not generic parameters (`:!`) so it's still not quite right.
