When I fixed 56947 in 4.7, I added an assert to make sure that the trunk
was being sensible in the way I expected: local class member functions
are supposed to be instantiated from the TAG_DEFN. But we can get to
instantiate_decl before that if it's used from another local class
member function, so the assert is wrong; let's just remove it.
Tested x86_64-pc-linux-gnu, applying to trunk.
