[ARM] Constant fold VCTP intrinsics

We can sometimes get into the situation where the operand to a vctp
intrinsic becomes constant, such as after a loop is fully unrolled. This
adds the constant folding needed for them, allowing them to simplify
away and hopefully simplifying remaining instructions.
