Currently we emit `DW_AT_deleted` for `deleted` special-member functions (i.e., ctors/dtors). However, in C++ one can mark any member function as deleted. This patch expands the set of member functions for which we emit `DW_AT_deleted`. The DWARFv5 spec section 5.7.8 says: ``` <non-normative> In C++, a member function may be declared as deleted. This prevents the compiler from generating a default implementation of a special member function such as a constructor or destructor, and can affect overload resolution when used on other member functions. </non-normative> If the member function entry has been declared as deleted, then that entry has a DW_AT_deleted attribute. ``` Thus this change is conforming.
