There are bunch of another builtins required for eh to execute properly.
The 3 most important one are:
- eh_return
- unwind_init
- dwarf_cfa

The first two precisely match to the gcc's ones, the third - slightly
differs, because is catches some extra information from the frontend.

With best regards, Anton Korobeynikov.
