I'll make the variable a bit clearer in the next update.  That's a good suggestion, thanks!

As for `ClangExecutable`, I haven't looked at where this is being defined.  It's indeed the driver name and not the name of the Clang driver.  So, for Flang is actually contains the full path to `flang-new`.

I'm not opposed to renaming it as part of this PR, but it may widen the scope and make approval a bit more complex.  So, my feeling is that this refactoring should take place in a different PR.  But I can be convinced otherwise.
