Make tag declarations redeclarable. This change has three purposes:
1) Allow the Index library (and any other interested client) to walk
the set of declarations for a given tag (enum, union, class,
whatever). At the moment, this information is not readily available.
2) Reduce our dependence on TagDecl::TypeForDecl being mapped down
to a TagType (for which getDecl() will return the tag definition, if
one exists). This property won't exist for class template partial
specializations.
3) Make the canonical declaration of a TagDecl actually canonical,
e.g., so that it does not change when the tag is defined.
