For aliases we never clear their body/blocks because they are never finalized.
If this is same_body_alias produced by C++ FE, I guess it should be responsible
for giving us a decl alone. Overall C++ FE is leaking quite a few bodies/trees
in unfinalized decls. I used to have aptch to clear them out but it was
rejected
for PCH reasons.
