[vm/compiler] Ensure that right operand range is set for ShiftUint32Op created during range analysis Code generation for shift instructions relies on the range information for the right operand in order to generate shifts by constants and omit certain runtime checks. When range analysis creates ShiftUint32Op it has not been setting range of the right operand, which resulted in suboptimal code. This change fixes that by using BinaryIntegerOpInstr::Make which initializes range of the right operand if it is a constant.

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.
Dart's 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.
