Michael Buch c146df9618 [clang][DebugInfo] Emit DW_AT_deleted on any deleted member function ...

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.
