  - Add ref-qualifiers to the type system; they are part of the
  canonical type. Print & profile ref-qualifiers
  - Translate the ref-qualifier from the Declarator chunk for
    functions to the function type. 
  - Diagnose mis-uses of ref-qualifiers w.r.t. static member
  functions, free functions, constructors, destructors, etc.
  - Add serialization and deserialization of ref-qualifiers.

was working before, but the false assumption that
'return' always appeared at the end of the block
was uncovered by a recent change.

I'm separately committing this because it incidentally changes some
block orderings and minor IR issues, like using a phi instead of
an unnecessary alloca.
