compiler: Add __designated_init annotation
This allows structure annotations for requiring designated initialization in GCC 5.1.0 and later: https://gcc.gnu.org/onlinedocs/gcc/Designated-Inits.html The structure randomization layout plugin will be using this to help identify structures that need this form of initialization.
