Fix two significant bugs in LSR: 1. When rewriting code in outer loops, sometimes we would insert code into inner loops that is invariant in that loop. 2. Notice that 4*(2+x) is 8+4*x and use that to simplify expressions. This is a performance neutral change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25964 91177308-0d34-0410-b5e6-96231b3b80d8
