There are a few places in the AST dumper where it prints hexadecimal pointer addresses. This can be useful when dumping nodes in the debugger, but it makes the output nondeterministic when can cause problems for build systems that cache outputs. In the JSON format only, replace these pointers with the string `"replaced-pointer-XX"`, where `XX` is an increasing integer ID. We keep track of the pointers that have been replaced so that the same pointer always maps to the same ID; this means that those nodes can still be related to each other when reading the AST later, if needed.
