Build: fix GCC 7 implicit fallthrough warnings (#769)
Fromhttps://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html:>C++17 provides a standard way to suppress the -Wimplicit-fallthroughwarning using [[fallthrough]]; instead of the GNU attribute. In C++11 orC++14 users can use [[gnu::fallthrough]];, which is a GNU extension.Instead of these attributes, it is also possible to add a fallthroughcomment to silence the warning.
