Thinking about this more, I think this isn't the right approach. A debug build
of Phobos/Druntime (with optimizations/inlining disabled and/or assertions
enabled) would definitely have a huge performance impact. We just need stack
frames, so that the user/debugger can read any stack traces that go through
Phobos.

I don't see how this is relevant. This is not about exception unwinding, but
seeing a stack trace in debugger or Druntime output so you know why your
program crashed.
