David Majnemer 6de0a12927 IR: Properly return nullptr when getAggregateElement is out-of-bounds
We didn't properly handle the out-of-bounds case for
ConstantAggregateZero and UndefValue.  This would manifest as a crash
when the constant folder was asked to fold a load of a constant global
whose struct type has no operands.

This fixes PR22595.
