Some distinct metadata nodes, e.g DICompileUnit, have implicit nullptrs inside them. Iterating over them with dyn_cast leads to a crash, change the behavior so that the nullptr operands are skipped. Add the test distinct-metadata-nullptr.ll which will crash if null pointers are not handled correctly.
