[PATCH] D32874: [JumpThreading] Change a dyn_cast that is already protected by an isa check to a static cast. Combine the with another static cast. NFC

================
Comment at: lib/Transforms/Scalar/JumpThreading.cpp:583
     // live-in value on any predecessors.
     if (isa<Constant>(Cmp->getOperand(1)) && Cmp->getType()->isIntegerTy()) {
+      Constant *CmpConst = cast<Constant>(Cmp->getOperand(1));
----------------
"Cmp->getType()->isIntegerTy()" is always true, so you could just make this "if (Constant *CmpConst = dyn_cast<Constant>(Cmp->getOperand(1)))".
