This patch defines flags for disabling speculative execution for GCC and Visual Studio and applies them to all binaries except libjvm when available in the compiler. It defines a new jvm feature no-speculative-cti, which is used to control whether to use the flags for libjvm. It also defines a new jvm variant "altserver" which is the same as server, but with this new feature added. I think the classic name for such product configuration is "hardened", no? I don't know. I'm open to suggestions on naming.

"hardened" sounds good to me.

The change looks good as well. /Jesper
