Hi,

the below seems to me a safe way to deal with this ICE, causing an
incomplete diagnostic in release mode too: do at the caller side, ie
instantiate_template, the check on matching levels which is asserted on
top of retrieve_specialization, and return error_mark_node in case of
failure: the callers of the former, at variance with the callers of the
latter, are prepared to deal with it.

Tested x86_64-linux. Ok for mainline?

Paolo.
