After I implemented a draft of PPCMachObjectWriter, I started seeing a few
DebugInfo test failures (code that was never reached before, most likely).

For example:

FAIL: LLVM :: DebugInfo/two-cus-from-same-file.ll (4009 of 7486)
******************** TEST 'LLVM :: DebugInfo/two-cus-from-same-file.ll' FAILED

********************

Observed since around r175024, around the time I made the first Mach-O/PPC
writer:
http://www.csl.cornell.edu/~fang/sw/llvm/logs/llvm-r175024b-powerpc-darwin8-g++-4.0.1-debug-check.log.bz2

So I need to figure out how to handle this somewhere near
lib/DebugInfo/DWARFContext.cpp
