[PATCH] D100118: [clang] Add support for new builtin __arithmetic_fence to control floating point optimization, and new clang option fprotect-parens

Thanks, that's better. The clang front-end option is not directly relevant for the semantic of the intrinsic, so it would be better to explicitly specify it was not being fuseable unless the operand degenerates into a single operand. Otherwise the specification sounds reasonable.
