[PATCH] llvm-3.1 port

[kallisti5]

a slight tweak is needed in projects/sample/autoconf/config.guess (someone used an *old* one without Haiku support)

[kallisti5]

... waiting for llvm to build before posting the diff :)

currently fighting the following failure:

first attempt, currently broken

 http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-May/049620.html seems to be related to the error above.

The updates to the autoconf tools in programs/sample was already done in llvm head, so 3.2 should remove the need for those changes.

3.2 works, so no need to work on 3.1.
