Remove AliasAnalysis metadata from LocalScope

[Akirathan]

LocalScope is used in many places. It is referenced by some runtime objects, like MethodRootNode. The problem is that LocalScope contains references to AliasAnalysis metadata (e.g., AliasGraph in https://github.com/enso-org/enso/blob/develop/engine/runtime-compiler/src/main/scala/org/enso/compiler/context/LocalScope.scala#L34).

Loading AliasAnalysis metadata in IrToTruffle is potentially very slow, as the size of the metadata is enormous. Therefore, we should avoid using AliasAnalysis metadata in IrToTruffle altogether. This first PR (#10729) removed some usages and introduced new, lightweight, FramePointer metadata. In this task, let's remove the references to AliasAnalysis metadata from LocalScope altogether.

Tasks

Preview Give feedback

1. Remove references to AliasAnalysis metadata from LocalScope.
2. Ensure that the startup time is improved
3. Try to apply Jaroslav's suggestion from Store FramePointer in IR #10729 (review)

Follow-up of #10129

[JaroslavTulach]

A step towards 10% speedup seems possible, but:

... still see more than 500 of AliasAnalysis metadata being read ... coming from EnsoRootNode.buildFrameDescriptor() - we need to find a build to build the descriptor ... without needing AliasAnalysis.

[JaroslavTulach]

Since #10837 the LocalScope can be constructed without loading AliasAnalysis data - if needed the data can be loaded later. Since #10906 we can build FrameDescriptor without loading these AliasAnalysis data at all. With #10996 we fix the caches to be able to load Hello_World.enso without needing any AliasAnalysis. To track use:

./enso --log-level trace --run xyz.enso | grep "] Scope"

I believe we are done.
