remove legacy i386 fallback stdarg implementation and framework
this has been slated for removal for a long time. there is
fundamentally no way to implement stdarg without compiler assistance;
any attempt to do so has serious undefined behavior; its working
depends not just (as a common misconception goes) on ABI, but also on
assumptions about compiler code generation internal to a translation
unit, which is not subject to external ABI constraints.
