Ping: https://gcc.gnu.org/pipermail/gcc-patches/2021-June/571975.html

the C and C++ front end changes to the new suppress_warning() API.

The attached patch replaces the uses of TREE_NO_WARNING in the shared
C family front end with the new suppress_warning(),
warning_suppressed_p(), and copy_warning() APIs.
