Make MDNode::destroy private.
Fix the one thing that used MDNode::destroy, outside of MDNode itself.

One should never delete or destroy an MDNode explicitly. MDNodes
implicitly go away when there are no references to them (implementation
details aside).

Do not try to insert local variable info to a DIE used for function declaration.

Relax assertion. In optimized code, it is possible that first instruction is coming from a inlined function.
This fixes PR7596 .

Reuse DIEInteger for 1. This is frequently used while emitting an attribute using dwarf::DW_FORM_flag form.

Keep track of abstract subprogram DIEs.
