  Log Message:
  -----------
  [DAG] ISD::is*Load/is*Store - merge isa<>/cast<> calls into single dyn_cast<>. NFCI.

cast<> repeats most of the work that isa<> will have already done (and even calls assert(isa<>) in debug builds) - just use dyn_cast and a pointer check to avoid all this duplicated work.
