QmlCompiler: Periodically trim register content pool
The code generator uses temporary register contents for various
purposes. None of those survive across instructions since there wouldn't
be anywhere to store them. We don't need to keep those temporaries
around until the end of the compilation. Trim them after each
instruction.
