Move the persistent variable counter into Target

Authored by aprantl on Apr 25 2018, 2:15 PM.



Move the persistent variable counter into Target so it can be shared across multiple language plugins.

In a multi-language project it is counterintuitive to have a result
variables reuse numbers just because they are using a different
language plugin in LLDB (but not for example, when they are
Objective-C versus C++, since they are both handled by Clang).

This is NFC on except for the Go plugin.

Thread an is_error flag through for plugins that need it.

Except for the inline comment, this is okay. If we thought hard we might find another likely reason why we'd want to use two result prefixes besides a language that has an error return side-channel. But I can't off the top of my head, so is_error is fine for now.

I'm sorry: which inline comment? Did you perhaps forget to hit "Submit"?

Eh, must have. The page really shouldn't let you overall submit if there are uncommitted comments, but whatever. Let's see if I did it right this time..

Don't hard-code "$" here, call GetPersistentVariablePrefix.
