More fixes to builtin preprocessor defines.

 - Add -static-define option driver can use when __STATIC__ should be
   defined (instead of __DYNAMIC__).

 - Don't set __OPTIMIZE_SIZE__ on Os, __OPTIMIZE_SIZE__ is tied to Oz.

 - Set __NO_INLINE__ following GCC 4.2.

 - Set __GNU_GNU_INLINE__ or __GNU_STDC_INLINE__ following GCC 4.2.

 - Set __EXCEPTIONS for Objective-C NonFragile ABI.

 - Set __STRICT_ANSI__ for standard conforming modes.

 - I added a clang style test case in utils for this, but its not
   particularly portable and I don't think it belongs in the test
   suite.
