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

CodeGen v2 permits template parameters to be qualified. This means that if we call `make_field` with a template parameter it will be qualified. However, we don't qualify the types when generating meta functions such as `NameProvider` and `TypeHandler`. This means these qualified types don't match up with the expected type. Use `std::decay_t` when forwarding the type to `NameProvider` and `TypeHandler` so they're always the base type that they were generated with. Most of this is covered by `make_field`, but there are direct references to `TypeHandler<Ctx, T>` in a lot of `TypeHandler::type` fields. Fix the problematic types manually for now, there may need to be a better solution with meta functions for this in the future. Test Plan: - CI - Added a test for `std::unique_ptr<const uint64_t>` to exercise this. Failed before, passes after. - Added a test for `std::unique_ptr<const std::vector<uint64_t>>` to test a non-primitive type. Failed before, passes after. |

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.
