Yep check out PR1324. Doing something like this would be a great improvement.

[LLVMdev] Fwd: How to force the creation of arrays with zeroes?
Hi Chris. The main question is how to implement ConstantAggregateXXXXX::getOperand? Should it be empty collection, or it must return the item aggregated?

[LLVMdev] Fwd: How to force the creation of arrays with zeroes?
Hi Anton, in a solution without CAZ, isNullValue can just return true when it
sees the special "this ConstantArray is all zero" flag. So all the places that
now look for CAZ can just use isNullValue instead and there need be no
performance loss. That said, CAZ is more "in your force" so less likely to be
forgotten about. Another interesting possibility is to handle more than
