Fix handling of deleted and templated constructors. (#6129)

Don't ignore deleted constructors in overload resolution. If one is the
best match, we want an error rather than picking something else. Don't
crash if we find a constructor template or other weird thing; use
`getConstructorInfo` to map it into a constructor and skip it if it
isn't one, like Clang does.
