Pointer layout support (#2930)

* WIP looking at reflection with pointers.

* Added GetPointerLayout.

* Initial test via reflection with layout of ptr type.

* WIP handles ptrs to types that have layout that hasn't been completed.

* Move tests to ptr.

* WIP try to take into account lowering correctly between AggTypeDecl and Type, but doesn't quite work.

* WIP a different path to handling recursive lowering problem with Ptr.

* Fix issues with reflection output.

* Small tidy.

* Fix for infinite recursion issue.

* Lower IRPointerTypeLayout

* Working with generics.
Has a hack to work around Layout around Ptr in IR.
The reflection around the generic - the name isn't much use, it should probably have the generic parameters, but that would require getName to do something more sophisticated.

* Fix issue around calling finishOuterGenerics to early.

* Remove feature/ptr test.

* Fix type legalization being an infinite loop with Ptr self referencing.

* Disable the pointer self reference test because produces an infintie loop on emit.

* Fixed comment based on review.

* Fix for issue with emit and pointers causing infinite recursion.
