Add memoization for getSCEVAtScope results for instructions which are not analyzed with SCEV techniques, which can require brute-forcing through a large number of instructions. This fixes a massive compile-time issue on 400.perlbench (in particular, the loop in MD5Transform). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@71259 91177308-0d34-0410-b5e6-96231b3b80d8
