This reverts commit 3c87c14457.
Reason for revert: Reverting parent CL.
Original change's description:
> [vm/compiler] Check non-constant supertypes for top types in AssertSubtype.
>
> This restores the invariant that the runtime entry is never run on
> instantiated top types.
>
> TEST=Run on trybots of all architectures, since existing tests cover static and dynamic AssertSubtype well.
>

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.
