There's an alias declaration for each template parameter. It is 
created so that one can refer to the template paramter in the 
scope matching to the template body.

There's already a micro optim for AliasDeclaration, see 
https://github.com/dlang/dmd/pull/11354. It should cut the use by 
25% (so the number for AliasDecl *only*), minus the problem of 
allocations blocks, so maybe more 10% to 20% IRL.
