// We can not assume that all containers have 8-byte alignment. However, to
// properly calculate alignment would require significant refactoring of
// the container identification code:
// - DrgnParser needs to return Class objects instead of Containers
// - They must be flattened
// - We must calculate alignment based on their members
// - Then we are able to convert them into Container objects
//
// As a quick, hopefully temporary solution, hardcode some known container
// alignments here
