Split out the Dwarf writer stuff into separate files. This is a much more
logical/sane approach to organizing all of the stuff that goes into writing out
DWARF information. Honestly? even this is too complex for what it's supposed to
be doing.
Trivia: It *looks* like there would be functionality changes, however there aren't!
