Make a deep copy of the result of a subquery in case the subquery is
reused.  Fix for the problem reported by
[forum:/forumpost/28216b36ac|forum post 28216b36ac] and introduced by
check-in [f30fb19ff763a7cb].  Further changes to try to optimize the new
OP_Copy opcode back into either OP_SCopy or OP_Move will be attempted
separately.  A test case will be in TH3.
