Nick Lewycky 4c93a0f092 Add a constant folding of casts from zero to zero. Fixes PR9011!
While here, I'd like to complain about how vector is not an aggregate type
according to llvm::Type::isAggregateType(), but they're listed under aggregate
types in the LangRef and zero vectors are stored as ConstantAggregateZero.
