In some specific scenarios, `Ptr.getElementType()` won't be a primitive type or a vector of primitive types, and thus `getScalarSizeInBits()` returns zero. Use the datalayout to get the proper size of the type instead of making an implicit assumption that the type is a simple primitive type. Solves SWDEV-534184
