@fw-immunant, I think you previously said this looked good, so if you could review quickly and we can merge it, that'd be great. I don't want #1306 to get too large, so I'd like to merge the simpler parts of it first.
…sion_test}` into `IndexMap`s instead of `HashMap`s Previously, `macro_invocations` was a `HashMap`, and thus iterating through it was unordered, which populated the `Vec<CExprId>` of `macro_expansions` non-deterministically, which then resulted in non-deterministic output from `--translate-const-macros conservative`. I also changed the other `macro_*` maps to `IndexMap`, as many other maps in `TypedAstContext` are already `IndexMap`s, too, and it's likely that we want these stably ordered and deterministic.
