`SPIRVEmitIntrinsics::simplifyZeroLengthArrayGepInst` asserted that it always expected a `GetElementPtrInst` from `IRBuilder::CreateGEP` (which returns a `Value`). `IRBuilder` can fold and return a `ConstantExpr` instead, thus violating the assertion. The patch fixes this by using `GetElementPtrInst::Create` to always return a `GetElementPtrInst`. This LLVM defect was identified via the AMD Fuzzing project.
