This would be much easier to read as a helper like:
```c++
static QualType getVectorElementType(ASTContext &Context, QualType VecTy) {
if (const auto *TyA = VecTy->getAs<VectorType>())
return TyA->getElementType();
if (VecTy->isSizelessVectorType())
return VecTy->getSizelessVectorEltType(Context);
return QualType();
}
```
(which already exists in SemaChecking, so maybe factor this to some common
code). Also, getSizelessVectorEltType looks like it already handles SVE and RVV
builtins (so does not need additional handling here).
