TemplateArgumentLocInventIterator default constructor should not exists

TemplateArgumentLocInventIterator() { }

because it doesn't and couldn't initialize Self member that is reference:
template<typename Derived, typename InputIterator>
class TemplateArgumentLocInventIterator {
TreeTransform<Derived> &Self;

Instantiation of this constructor is always a compile-time error.

Please note, that I didn't run any tests, because cannot imagine situation where this constructor can be properly used. There are no new tests for this fix for the same reason.

Ping?
How long it usually takes to merge already reviewed PR? Is something else expected from my side?

@Smertig Congratulations on having your first Pull Request (PR) merged into the LLVM Project!

Your changes will be combined with recent changes from other authors, then tested
by our build bots. If there is a problem with a build, you may receive a report in an email or a comment on this PR.

Please check whether problems have been caused by your change specifically, as
the builds can include changes from many authors. It is not uncommon for your
change to be included in a build that fails due to someone else's changes, or
infrastructure issues.

How to do this, and the rest of the post-merge process, is covered in detail here.

If your change does cause a problem, it may be reverted, or you can revert it yourself.
This is a normal part of LLVM development. You can fix your changes and open a new PR to merge them again.

If you don't get any reports, no action is required from you. Your changes are working as expected, well done!
