This is going to change. Intel recently released the ISA for Knights
Corner, a machine with general predication for SIMD.

[LLVMdev] Predication on SIMD architectures and LLVM
Hi,
I've done work on predicated SIMD representations for LLVM.
If you search through the archives, you may find my "applymask" proposal,
which is an attempt at representing predication in a very comprehensive
way. I've since stopped pushing the proposal in part because Larrabee's
changing fortunes led to a decline of interest at the time, in part because

[LLVMdev] Predication on SIMD architectures and LLVM
Hello,
I'm working on a compiler based on LLVM for a SIMD architecture that
supports instruction predication. We would like to implement branching
on this architecture using predication.
As you know the LLVM-IR doesn't support instruction predication, so I'm
not exactly sure on what is the best way to implement it.
We came up with some ways to do it in LLVM:
- Do not add any
