This change introduces 2 new stubs, InitLateInstanceField and InitLateFinalInstanceField. Those stubs call field initializer directly without going to runtime. Fixes the regressions on Uri.pathSegments.easy and Uri.pathSegments.hard.normalized benchmarks with NNBD SDK after https://dart-review.googlesource.com/c/sdk/+/143189.

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.
