syntax: convert ast_map to use a SmallIntMap.
NodeIds are sequential integers starting at zero, so we can achieve some memory savings by just storing the items all in a line in a vector. The occupancy for typical crates seems to be 75-80%, so we're already more efficient than a HashMap (maximum occupancy 75%), not even counting the extra book-keeping that HashMap does.
