This patch allows i386 signal delivery to work correctly when userspace is
compiled with -mregparm.  This is somewhat hacky: it passes the arguments
*both* on the stack and in registers, but it works because there are only
one or three (depending on SA_SIGINFO) official arguments.  If you're
relying on the unofficial arguments then you're doing something nonportable
anyway and can put in the __attribute__((cdecl,regparm(0))) in the correct
place.
