Michael Gottesman cb2d7560a4 [rbi] Fix demangling of sending results. ...

The issue here is that the demangler (since we have a postfix mangling) parses
parameters/results/etc and then uses earlier postfix type arguments to attach
the relevant types to the parameters/results/etc. Since the flag for a sending
result was placed in between the parameters and results, we get an off by one
error.

Rather than fix that specific issue by introducing an offset for the off by one
error, I used the fact that the impl-function part of the mangling is not ABI
and can be modified to move the bit used to signify a sending result to before
the parameters so the whole problem is avoided.

I also while I was doing this looked through the sending result mangling for any
further issues and fixed them as I found them.
