Kostya Kortchinsky a51139046e [scudo] Add Chunk::getSize, rework Chunk::getUsableSize 
Summary:
Using `getActuallyAllocatedSize` from the Combined resulting in mediocre
compiled code, as the `ClassId != 0` predicament was not propagated there,
resulting in additional branches and dead code. Move the logic in the frontend,
which results in better compiled code. Also I think it makes it slightly easier
to distinguish between the size the user requested, and the size that was
actually allocated by the allocator.

`const` a couple of things as well.

This has no functional impact.
