>From my reading, there's nothing obviously wrong with this patch,
except that it's too big, which makes reviewing it a lot more
difficult.  Please put the DeclBase code movement into a separate
patch (moving the DeclBase code is fine without review), put the
DeclChain changes into a separate patch, put the Decl::Struct ->
TagDecl::TK_struct changes into a separate patch, and split out
anything else that's obviously independent.

Minor issue I spotted: in CXXMethodDecl::getThisType, there's no point
to making "this" const; it isn't an lvalue, so the const modifier
doesn't do anything.
