because moden processos can store multiple values in parallel, and preparing the consecutive store requires some work. We only handle these cases: 1. Consecutive stores where the values and consecutive loads. For example: int a = p->a; int b = p->b; q->a = a; q->b = b; 2. Consecutive stores where the values are constants. Foe example: q->a = 4; q->b = 5; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164885 91177308-0d34-0410-b5e6-96231b3b80d8
