Summary

Remove .CUDAIsDevice flags from CodeGenOpts as it's already available
in LangOpts.

[eliben]

LGTM

I'd ask pcc@ if he remembers why this was ever created, just out of curiosity

The functionality itself is necessary and this one predates the langopt by
3 years. Probably just a lack of migrating the code when it was moved to
langopt.
