clang-p2996/clang/test/Analysis/cfg-rich-constructors.cpp
Artem Dergachev 8ac6c9dd67 [CFG] [analyzer] Allow elidable copies to have more than one arguments. 
Copy-constructors and move-constructors may have default arguments. It is
incorrect to assert that they only have one argument, i.e. the reference to the
object being copied or moved. Remove the assertion.
