## Summary Garbage collect ASTs once we are done checking a given file. Queries with a cross-file dependency on the AST will reparse the file on demand. This reduces ty's peak memory usage by ~20-30%. The primary change of this PR is adding a `node_index` field to every AST node, that is assigned by the parser. `ParsedModule` can use this to create a flat index of AST nodes any time the file is parsed (or reparsed). This allows `AstNodeRef` to simply index into the current instance of the `ParsedModule`, instead of storing a pointer directly. The indices are somewhat hackily (using an atomic integer) assigned by the `parsed_module` query instead of by the parser directly. Assigning the indices in source-order in the (recursive) parser turns out to be difficult, and collecting the nodes during semantic indexing is impossible as `SemanticIndex` does not hold onto a specific `ParsedModuleRef`, which the pointers in the flat AST are tied to. This means that we have to do an extra AST traversal to assign and collect the nodes into a flat index, but the small performance impact (~3% on cold runs) seems worth it for the memory savings.
