Alex Hoppen 56a923475f [libSyntax] Reference count SyntaxData ...

Instead of having a heap-allocated RefCountedBox to store a SyntaxData's
parent, reference-count SyntaxData itself. This has a couple of
advantages:
 - When passing SyntaxData around, only a pointer needs to be passed
   instead of the entire struct contents. This is faster.
 - We can later introduce a SyntaxDataRef, which behaves similar to
   SyntaxData, but delegates the responsibility that the parent stays
   alive to the user. While sacrificing guaranteed memory safety, this
   means that SyntaxData can then be stack-allocated without any
   ref-counting overhead.
