gallivm: Translate all util_cpu_caps bits to LLVM attributes.
This should prevent disparity between features Mesa and LLVM
believe are supported by the CPU.
http://lists.freedesktop.org/archives/mesa-dev/2015-October/thread.html#96990
Tested on a i7-3720QM w/ LLVM 3.3 and 3.6.
v2: Increase SmallVector initial size as suggested by Gustaw Smolarczyk.
