  Log Message:
  -----------
  TypeInfo records more information about align requirement

Extend the information preserved in `TypeInfo` by replacing the `AlignIsRequired` bool flag with a three-valued enum, the enum also indicates where the alignment attribute come from, which could be helpful in determining whether the attribute should overrule.
