The current series is just a simple transform of the existing code.
I think your proposed approach would work ok, though the current code
returns "main" even if it isn't defined in the program -- so we'd need
some extra hack for that.  I'll add a note about this.

If we ever want to support DW_AT_main_subprogram, we'll need some other
changes as well, since multiple functions can be marked that way.
