<pre>X86 optimization guide directly states that 32-byte alignment of small loops
may benefit from LSD(Loop Stream Detector) if some condition are met.
It seems that X86 LLVM backend does nothing related to this.
It would be nice to implement this optimization to speed-up execution of small
loops.</pre>
