Hamish Knight	4716f61fba	[AST] Introduce explicit actions for ASTWalker ... Replace the use of bool and pointer returns for `walkToXXXPre`/`walkToXXXPost`, and instead use explicit actions such as `Action::Continue(E)`, `Action::SkipChildren(E)`, and `Action::Stop()`. There are also conditional variants, e.g `Action::SkipChildrenIf`, `Action::VisitChildrenIf`, and `Action::StopIf`. There is still more work that can be done here, in particular: - SourceEntityWalker still needs to be migrated. - Some uses of `return false` in pre-visitation methods can likely now be replaced by `Action::Stop`. - We still use bool and pointer returns internally within the ASTWalker traversal, which could likely be improved. But I'm leaving those as future work for now as this patch is already large enough.	2022-09-13 10:35:29 +01:00
