[LLVMdev] Build error fails at MachineInstr const* for the past two days

[Marc J. Driftmeyer]

Andrew,

What every bit of code committed to trunk this afternoon did the trick. 
Compiles cleanly against gcc and clang-trunk from a few days prior.

I'll be precise on trunk revisions in the future as well as a more 
in-depth analysis of what trips, and when it trips. If I knew the inner 
workings of LLVM/Clang I'd be of much greater use.

Thank you for the fixes.

- Marc
