c++: block copy elision in delegating ctor
CWG2403 deals with the issue that copy elision is not possible when the
initialized object is a potentially-overlapping subobject and the
initializer is a function that returns by value. Jonathan pointed out that
this also affects delegating constructors, which might be used to construct
a base subobject.
gcc/cp/ChangeLog:
* call.cc (unsafe_return_slot_p): Return 2 for *this in a
constructor.
gcc/testsuite/ChangeLog:
* g++.dg/init/elide8.C: New test.
