pin down arg() stride (a.k.a. type) info sooner

Arg strides are the reason JIT happens lazily in Program::eval() today
instead of proactively in Builder::done() or Program's constructor.  It
also just really doesn't make sense to delay this information... it's
not like you can change it up sanely between calls to eval().

The argument index now comes implicitly from the order of calling arg().
This may seem logically independent, but it prevents a weird situation
where you could use the same argument index twice with different
strides... not sure what that would mean.
