Vyacheslav Egorov c3d8f46c5b [vm/compiler] Devirtualize calls while inlining. ... Inlined functions might contain call-sites which can be devirtualized in the context of the caller. To achieve that we add a pass which calls canonicalization on all dynamic calls (and their data dependencies) between rounds of inlining. More specifically this helps cases which require interleaving some redundancy elimination and inlining to remove the cost of abstractions. The primary example is for-in loop with an array of a known type which usually requires inlining `get:iterator` and propagating iterable value through interator's fields to specialize and inline `get:length` and `operator[]` on the `Iterable`. See https://github.com/dart-lang/sdk/issues/48433 for example.
