Driver: Implement Darwin_X86 tool chain level argument translation.
- This is really gross, but its the easiest way to match gcc. Once we
are confident in the driver, we can try and push these translations
down into tools.
- No test cases for this yet, it's hard to see the effects of these
translations before the gcc tool argument translation is pulled
over.
- Interaction with "unused argument" warning hasn't been worked out
yet.
- <rdar://problem/
6717359> [driver] implement toolchain specific
argument translation.
"It's horrible in here."
