```
dwarf: optimize dwarf parsing for speed

This code is run when printing a stack trace in a debug executable, so
it has to be fast even without compiler optimizations.

Adding a `@panic` to the top of `main` and running an x86_64 backend
compiled compiler goes from `1m32.773s` to `0m3.232s`.

```
