	PR fortran/83763
	* trans-decl.cc (gfc_trans_deferred_vars): Ensure that the
	parameterized components of PDTs that do not have allocatable
	components are deallocated on leaving scope.
	* trans-expr.cc (gfc_trans_assignment_1): Do a dependency check
	on PDT assignments. If there is a dependency between lhs and
	rhs, deallocate the lhs parameterized components after the rhs
	has been evaluated.
