`KernelLoader::FinishClassLoading` was leaving guarded state of this field in an inconsistent state: it was setting guarded cid to `kDynamicCid`, but not setting guarded length to `kNoFixedLength`. As a result in JIT mode we would generate stale length guards for these fields and these guards would inhibit allocation sinking. This CL fixes this.

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.
