Kernel that causes the segfault

I get a segmentation fault in LLVM with Tom Stellard's recent radeonsi compute
patches
(http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20130520/175743.html)
with the attached kernel.

I can work around the issue when executing the if-block in the kernel
unconditionally or with the attached patch to LLVM.
Desc.OpInfo[0].RegClass equals -1 when the segmentation fault occurs.
