Make exceptions throughout the GCC code base consistent. Over the years, as new files were added to GCC that needed to carry this license exception, we reviewed and updated the language to help clarify it and address new concerns. As a result, there are now many different exception texts in GCC that provide the same basic permissions. Now all of those files will be able to use the single new exception text that we've prepared, making it easier to perform legal reviews on the code.
