Object Introspection (OI) enables on-demand, hierarchical profiling of objects in arbitrary C/C++ programs with no recompilation.

Summary: We have a good type representation in the Type Graph of an incomplete type and the underlying type that represents. However, this incomplete type still ends up in the generated code as `void` which loses information. For example, a container that can't contain void may fail to compile because it was initialised with `void` but really its because the type it was supposed to be initialised with (say, `Foo`) had incomplete debug information. This change identifies that a type is incomplete in the output by generating it as an incomplete type `struct Incomplete<struct Foo>`. This allows us to name the type correctly in the TreeBuilder output and filter for incomplete types, as well as getting appropriate compiler errors if it mustn't be incomplete. Test Plan: - CI - Added a unit test to namegen. - Enabled and added an extra pointers_incomplete test. This change is tricky to test because it isn't really user visible. The types still use their `inputName` which is unchanged in any successful output - this change is used so the compiler fails with a more detailed error. |

object-introspection
Object Introspection is a memory profiling technology for C++ objects. It provides the ability to dynamically instrument applications to capture the precise memory occupancy of entire object hierarchies including all containers and dynamic allocations. All this with no code modification or recompilation!
For more information on the technology and how to get started applying it to your applications please check out the Object Introspection website.
