This PR replaces
IRType
withType
in the IR-based use-use dataflow library. This change is needed to remain compatible with thegetType
in the old AST-based dataflow library. And in fact, I think using Type here makes more sense since this is often the type people want to use for dataflow queries.The main point of this PR is done in the last commit. The first commit is a refactoring PR that should be behavior-preserving, and the second commit is a slight performance change that reduces the number of dataflow nodes generated from IR operands.
