Nick Desaulniers d01b425e5d Add -Wimplicit-fallthrough checks if supported ... Clang since r369414 (clang-10) can now check -Wimplicit-fallthrough for C code, and use the GNU C style attribute to denote fallthrough. Move the test from header only to autoconf. The previous test used brittle version detection which did not work for newer clang that supported this feature. The attribute has to be its own statement, hence the added `;`. It also can only precede case statements, so the final cases should be explicitly terminated with break statements.
