Determine whether we're currently on the alternative signal stack
dynamically, by comparing the stack pointer against the altstack
base and size, so that you get the correct answer if you longjmp
out of the signal handler, as tested by regress/sys/kern/stackjmp/.
Also, fix alt stack handling on vax, where it was completely broken.
Testing and corrections by miod@, krw@, tobiasu@, pirofti@
