[C++ Patch] PR 50732

Subject: [C++ Patch] PR 50732

Hi,

submitter complains that, at variance with C++11, __is_base_of doesn't handle an incomplete base type (the first parameter). The reason seems simple: in finish_trait_expr we try to complete *both* types instead of doing it where/when necessary.

Tested x86_64-linux. Ok?

Thanks,
Paolo.
