================
Comment at: lib/Analysis/ConstantFolding.cpp:550-552
// If we're not accessing anything in this constant, the result is undefined.
if (Offset >= InitializerSize)
return UndefValue::get(IntType);
----------------
Is `Offset==0` == 0'th byte of the constant?
If so, perhaps this check could simply be done first?
