Liam Appelbe 331067017f [vm] Fix late field store bug 
Late field stores were being incorrectly marked as initializations,
causing them to be incorrectly optimised out in some cases.

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.
