Alexander Markov 994f454996 [vm/nnbd] Call field initializer from stubs for late instance fields
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.
