Slava Pestov 1c3ac86796 AST: Banish OptionalTypeKind to ClangImporter.h ...

The only place this was used in Decl.h was the failability kind of a
constructor.

I decided to replace this with a boolean isFailable() bit. Now that
we have isImplicitlyUnwrappedOptional(), it seems to make more sense
to not have ConstructorDecl represent redundant information which
might not be internally consistent.

Most callers of getFailability() actually only care if the result is
failable or not; the few callers that care about it being IUO can
check isImplicitlyUnwrappedOptional() as well.
