The virtual method `ProgramPointTag::getTagDescription` had two very distinct use cases: - It is printed in the DOT graph visualization of the exploded graph (that is, a debug printout). - The checker option handling code used it to query the name of a checker, which relied on the coincidence that in `CheckerBase` this method is defined to be equivalent with `getName()`. This commit switches to using `getName` in the second use case, because this way we will be able to properly support checkers that have multiple (separately named) parts. The method `reportInvalidCheckerOptionName` is extended with an additional overload that allows specifying the `CheckerPartIdx`. The methods `getChecker*Option` could be extended analogously in the future, but they are just convenience wrappers around the variants that directly take `StringRef CheckerName`, so I'll only do this extension if it's needed.
