Clean up the C++0x __has_feature tests. Specifically:
- Don't publicize a C++0x feature through __has_feature if we aren't
in C++0x mode (even if the feature is available only with a
warning).
- "auto" is not implemented well enough for its __has_feature to be
turned on.
- Fix the test of C++0x __has_feature to actually test what we're
trying to test. Searching for the substring "foo" when our options
are "foo" and "no_foo" doesn't work :)
