llvmpipe: Fallback to element-wise comparisons when no comparison intrinsic is available.
Although selection of vector elements is valid LLVM IR, no machine target
supports it yet.
This is a last-resort option, but it allows llvmpipe to be used on any
target supported by LLVM without modifications. Obviously better
performance is attainable by emitting SIMD intrinsics where otherwise
LLVM doesn't.
