Reland "[vm/compiler] Consistently use PointerBase.data values as FFiIntPtr."

This is a reland of commit 5c4fd506676ced39567c0383b1bb643668eb0222

The range analysis change was replaced with a different change,
on which this CL is based. In addition, another preceding CL
unified a few methods on subclasses of UnboxIntegerOpInstr, because
the inconsistencies between UnboxInt32OpInstr and UnboxUint32OpInstr
and how unboxed int32 vs. uint32 constants were handled caused the
issue seen after landing the original CL.

Thus, this CL is purely changes of kUnboxedIntPtr to kUnboxedFfiIntPtr
when appropriate plus test changes.

Original change's description:
> [vm/compiler] Consistently use PointerBase.data values as FFiIntPtr.
>
> Also if converting an unboxed int with only non-negative values
> that fit in 32 bits to a uint32, then keep the range from the value.

Dart

A client-optimized language for fast apps on any platform

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'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).
