This is the final part of the initial DWARF debugging work. It implements support for dealing with inlined function calls, such that inline functions appear as normal in the stack, and stepping works. This also improves stepping overall, such that stepping goes between statements rather than assembly instructions.
The linked docs briefly explain how inlined functions work in their API. The largest chunk of code in this PR is refactoring the stacktrace functionality to support these 'fake' callframes.
