Dan Gohman 6bce643c36 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).
