In the verify-only pass, check that items that don't have an initializer in an init list can be value-initialized, at least when designated initializers are not involved. No test case yet, since early failures cannot be distinguished from late failures until overload resolution works.

When we determine that a function template specialization produced as
...
part of template argument deduction is ill-formed, we mark it as
invalid and treat it as a deduction failure. If we happen to find that
specialization again, treat it as a deduction failure rather than
silently building a call to the declaration.
Fixes PR11117, a marvelous bug where deduction failed after creating
an invalid specialization, causing overload resolution to pick a
different candidate. Then we performed a similar overload resolution
later, and happily picked the invalid specialization to
call... resulting in a silent link failure.
