This adds something like 'align 4' to the runtime.alloc calls, so that the compiler knows the alignment of the allocation and can optimize accordingly. The optimization is very small, only 0.01% in my small test. However, my plan is to read the value in the heap-to-stack transform pass to make it more correct and let it produce slightly more optimal code.
