Decompose GVN::processNonLocalLoad() (about 400 LOC) into smaller helper functions. No function change. This function consists of following steps: 1. Collect dependent memory accesses. 2. Analyze availability. 3. Perform fully redundancy elimination, or 4. Perform PRE, depending on the availability Step 2, 3 and 4 are now moved to three helper routines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181047 91177308-0d34-0410-b5e6-96231b3b80d8
