The UB fixes are the ones I am picking up in https://reviews.llvm.org/D101206. These fixes are about ensuring that we begin and end the lifetime of node classes, which are currently never created. We allocate the nodes and then we construct their various members individually, but we never actually call their constructor or destructor.
