This change is going to have a very interesting impact on debuggability. It will make these types a lot easier to understand in the debugger since `__compressed_pair` was really difficult to inspect.

However, it will require a change in the LLDB data formatters almost 100% certain, CCing @Michael137. Michael, we're basically changing the names of members for a lot of types for which there are LLDB formatters, and it would be nice to avoid breaking LLDB when we do that.
