Revert "[vm] Mark snapshots that were compiled directly to ELF."

This reverts commit 250b84987d6b439c36e0f7e8be6ee0a7c0be68c8.

Reason for revert: Failures on FFI CI tests.

Original change's description:
> [vm] Mark snapshots that were compiled directly to ELF.
> 
> Since the virtual addresses in ELF snapshots are the same as in
> separately saved debugging information, print the virtual address in
> non-symbolic frames again when running from a snapshot compiled directly
> to ELF.

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).
