Ryan Macnak 2d207f49cc [vm, compiler] Adjust the write barrier stub to no longer assume there is no race when setting the remembered bit.

Failure to check for losing the race can result in the same object being added to the remembered set twice, and processing the remembered set is not idempotent.

Previously there could be no such race, but the combination of lazy initialized const maps/sets and isolate groups means that now more than one Dart thread can be writing to the same object.

Dart VM Compilation Pipeline

This folder contains Dart VM compilation pipeline.

Compilation pipeline is mainly responsible for converting AST or Kernel AST into IL flow graphs and then generating native code from IL.

It has the following structure:

Directory	What goes there
`assembler/`	Assemblers and disassemblers
`backend/`	IL based compilation backend: optimization passes and architecture specific code generation rules
`frontend/`	Frontends responsible for converting AST into IL
`jit/`	JIT specific passes and compilation pipeline entry points
`aot/`	AOT specific passes and compilation pipeline entry points
`.`	Shared code or code without clear designation.

Currently there are no layering restrictions and components from different subfolders can reference each other.
