[PATCH] Automated handling of language options for attributes

[Richard Smith]

I guess the intent is to eventually switch over to generating
include/clang/Basic/LangOptions.def with tablegen, with a shared .td file
being used for both that and the attributes?

Please name your generated functions with a leading lowercase letter
("defaultDiagnoseLangOpts", "checkCPlusPlusLangOpts"); other than that,
LGTM. Thank you!
