e6bd9c9780 Add a new TypeWalker, similar to ASTWalker but for types.
Use it to replace the switch-based implementation of Type::findIf. This
will also be used for typealias recursive inheritance checking and for
swift2objc forward declarations.

a70eff6609 Introduce TypeRepr and related subclasses, that is a representation of a type as written in source.
This the first part for improving source location fidelity for types,
changes to follow:

-The Parser will not create any types, it will just create TypeReprs.
-The type checker will create the types by going through TypeReprs.
-IdentifierType will be removed.

8deec52b17 Rework AST representation of CaseStmts.
A single case block can have one or more 'case ...:' labels. 'case' labels contain patterns instead of exprs. 'default:' is a funny spelling for 'case _:'. Change the CaseStmt representation and rip out all the parsing, type-checking, and SILGen built off the old representation.
