Based on the unified typed data layout, we can now inline accesses to typed data interface classes if there are no 3rd party implementations of those interfaces. Example: If a receiver is of type Uint8List and we call `[]` or `[]=` we will inline the byte access. Instead of changing the existing inliner / call specializer we add this as an extra pass: If the inliner / call specializer infer that the receiver type is e.g. internal typed data then it will perform the inlining itself using more optimized LoadIndexed instruction. => Only if those existing optimization passes have not been able to inline the access will we, later on in the compilation pipeline, run a specialized pass which will inline the accesses using LoadUntagged + LoadIndexed (which is slightly less efficient than using only LoadIndexed for internal typed data). As a first step this is only done for AOT. For ease of writing tests matching certain IR graphs this CL also adds a IR pattern matcher.
