Creates VarHandleOps right next to the operations that use them, one
per operation.
This is useful for transformations that only end up with a few small
snippets of remaining TF code, and wish for those snippets to be
self-contained.
For example, this would transform

"tf_saved_model.global_tensor"() { sym_name = "v" ... }
func @f(%arg0 {tf_saved_model.bound_input = @v}) {
  %1 = "tf.ReadVariableOp"(%arg0)
  ...
}
