Support arbitrary parameter forms in MakeGeneratedFunctionDecl (#7654)

Browse Source 
This allows generated functions to have different forms for different
parameters, and by-ref or by-value return forms. As a byproduct, this
allows generated functions to supply a return type _inst_ ID when they
have one, which preserves things like location information.
