Thanks for the reviews @tblah and @mjklemm.

As `OmpAttributeVisitor::Post(const parser::Name &name)` was becoming quite complex, I have refactored it in the last commit. The main changes were:
- Move IsPrivatizable to a separate function.
- Move the code that handles symbols with implicitly determined DSAs to a separate function, `CreateImplicitSymbols`, undoing most changes from the first commit in this part.

This allowed the logic that handles statement function symbols to be simplified. Now we just need to collect non-dummy argument symbols from statement functions and call `CreateImplicitSymbols` for each of them.
