Add an extra parameter to __smear functions to encode return type.

Browse Source 
Now, the __smear* functions in generated C++ code have an unused first
parameter of the desired return type; this allows us to have headers
that include variants of __smear for multiple target widths.  (This
approach is necessary since we can't overload by return type in C++.)

Issue #256.
