The phi translated pointer can be computed when returning a partially cached result
instead of stored. This reduces memdep memory usage, and also eliminates a bunch of weakvh's. This speeds up gvn on gcc.c-torture/20001226-1.c from 23.9s to 8.45s (2.8x) on a different machine than earlier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91885 91177308-0d34-0410-b5e6-96231b3b80d8
