Streamability analysis for streamable function calls

This bug report is related to bug 25679 and action item ACTION-2014-10-16-005.

The resolution of bug 25679 seems to have not (yet) been completely implemented
in the spec, esp. comment#3 (which refers to comment#1). The essence of this
change was to allow more input postures to a function without changing the
default posture of the streamed parameter.

Two things:
1) the new rules have not been fully implemented, leading to incomplete
analysis
2) other arguments of the function call are not part of the streamability
analysis (essentially, they follow the default streamability rules)

In a private conversation with Michael Kay I proposed one solution that I
believe works, provided here for reference. An alternative solution is also
still in the mail (which changes less words) but I wasn't 100% it was correct
(this proposal I believe is correct).
