[vm] Avoid local labels in assembly snapshots.
Labels starting with L are treated as local by the assembler
and cause problems down the line. When targeting ARM64 Mach-O
having local labels cause linker to break when trying to
generate compact unwinding information with a cryptic error
ld: too many compact unwind infos in function <...>
This happens because local labels are not seen as function
boundaries and multiple .cfi_startproc/.cfi_endproc are
mashed into a single function.

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).
Dart is free and open source.
