...which have a ucontext_t but not a PC register. The current stack unwinding implementation does not yet support this architecture. Also fix name of `std.debug.SelfInfo.openSelf` to remove redundancy. Also removed this hook into root providing an "openSelfDebugInfo" function. Sorry, this debugging code is not of sufficient quality to offer a plugin API right now.
