Something that is scoped by nature only pertains to the current thread and thus is implicitly synchronised. Furthermore, in memory-scope's case the alloc-free events are synchronised anyway which makes it redundant for the scoped events.

-Nanite-specific settings for tangent and degenerates are no longer also applied to the non-nanite mesh LODs on the same mesh.
-100% fallback meshes now have identical tangents to input mesh. Don't skip the tangent generation in StaticMeshBuilder for these meshes and don't recalculate tangents in Nanite builder.

-only particle systems will have their attributes compressed
-Previous versions of our deny list will also be denied compression (we don't want to be comparing half Particles.Prevoius.Position with float Particles.Position)
-fixed stride being supplied to VF shaders

C = A; // <-- this would get GetSecondValue() assigned to C instead of GetFirstValue()
Adds an SSA pass to help reduce overwriting registers, adds logic to remove self assignments, and adds logic to stop propagating when values are dirtied
From a sampling of scripts, about 2% are changed (where 1-3 unnecessary ops have been deleted).

These now serialize a NetGUID tracked by the PackageMap, as other replicated references to objects do. Effectively acts as a weak pointer in the replication case now as well. Soft pointers to stably-named objects continue to replicate their string path.
Added EngineTest cases for replicated soft pointers.
