[vm] Make --dwarf-stack-traces only have effects in precompiled mode.

Currently, turning on --dwarf-stack-traces can cause the flow graph
compiler to fail in JIT mode. In addition, non-symbolic stack traces can
be useless in JIT mode if recompilation happens and thus there's no
DWARF information for the new code.

Thus, change code that uses the flag to also check for precompiled mode,
so it doesn't change compilation or serialization for JIT snapshots, and
only produce non-symbolic stack traces in the precompiled runtime when
it is on.

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).
