Reason for revert: broke building Flutter apps in release mode
Original change's description:
> [vm,aot] Simple unreachable code elimination before type-flow analysis, take 2
>
> This is the relanding of https://dart-review.googlesource.com/c/sdk/+/121500
> with fixes.
>
> Original CL description:
>
> This change adds transformation for very early cleanup of unreachable
> code such as code guarded by if statements with constant conditions or
> code used in assert statements when assertions are disabled.
>
> The advantage of cleaning such code early is that type-flow analysis
> won't be looking at it and TFA-based tree shaker is able to remove
> more code.
