Add support for the "sec" extension (security extensions). We've been getting away without support for the sec extension because it's bogusly enabled even on arches where its presence is optional. This support for .arch_extension is being added mainly so that we can use the right directives in our source code, and that helps folks using external toolchains (and will help us when we finally update our toolchain).
