Detailed Description

DeclarationNameExtra is used as a base of various uncommon special names.

This class is needed since DeclarationName has not enough space to store the kind of every possible names. Therefore the kind of common names is stored directly in DeclarationName, and the kind of uncommon names is stored in DeclarationNameExtra. It is aligned to 8 bytes because DeclarationName needs the lower 3 bits to store the kind of common names. DeclarationNameExtra is tightly coupled to DeclarationName and any change here is very likely to require changes in DeclarationName(Table).
