[vm/compiler] Merge cid ranges when generating receiver check This change adds merging of cid ranges into Cids::Create if there are gaps with the same target function. Previously, this optimization was performed only when calculating targets via CallTargets::CreateAndExpand. However, Cids::Create is widely used to check receiver type if there is only one targets (e.g. in CallSpecializer::AddReceiverCheck / CallSpecializer::AddChecksForArgNr). This optimization is needed to shrink huge code for CheckClass instructions in Flutter RenderObject.layout() method in JIT mode.

Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web
Dart has flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
