Richard Smith 58c3cc12da C++ core issue 1344, PR10618: promote "addition of default argument makes this
a special member" diagnostic from warning to error, and fix the cases where it
produced diagnostics with incorrect wording.

We don't support this as an extension, and we ban it even in C++98 mode. This
breaks too much (for instance, the ABI-specified calling convention for a type
can change if it acquires a copy constructor through the addition of a default
argument).

Alexis Hunt d051b87160 Implement a new warning for when adding a default argument to a method
makes it into a special member function. This is very bad and can lead
to all sorts of nastiness including implicit member functions violating
the One Definition Rule. This should probably be made ill-formed in a
later version of the standard, but for now we'll just warn.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Douglas Gregor ff7028a55e Revert r88718, which does NOT solve the constructor-template-as-copy-constructor issue. Big thanks to John for finding this

Douglas Gregor 5f235a21eb A constructor template cannot be instantiated to a copy
constructor. Make sure that such declarations can never be formed.
