Fix the code that checked if a SCEVAddRecExpr Start contains an addrec in a different loop to check the value being added to the accumulated Start value, not the Start value before it has the new value added to it. This prevents LSR from going crazy on the included testcase. Dale, please review. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64440 91177308-0d34-0410-b5e6-96231b3b80d8

; IV users in each of the loops from other loops shouldn't cause LSR

Change these tests to use regular loads instead of llvm.x86.sse2.loadu.dq. Enhance instcombine to use the preferred field of GetOrEnforceKnownAlignment in more cases, so that regular IR operations are optimized in the same way that the intrinsics currently are. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64623 91177308-0d34-0410-b5e6-96231b3b80d8

Fix the code that checked if a SCEVAddRecExpr Start contains an addrec in a different loop to check the value being added to the accumulated Start value, not the Start value before it has the new value added to it. This prevents LSR from going crazy on the included testcase. Dale, please review. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64440 91177308-0d34-0410-b5e6-96231b3b80d8
