This patch helps to eliminate more loads in loops with the omp simd pragma,
as part of the GVN pass.
This pragma indicates groups of load/stores that we know are not
aliasing. Through better alias analysis, we can find more accurately
a memory access which provides the same data as the loads
we want to eliminate.
