There are methods to build new types on ASTContext.

I'm currently trying to construct a new FunctionType using get methods on the previous type to fill in the parts that remain constant. The problem at the moment is that isVariadic() seems to be private but I presume that function types cannot be Variadic so I'll just pass false there and then try setType.
There are two kinds of FunctionType: FunctionProtoType and
FunctionNoProtoType. They need to be handled slightly differently.

There are some existing pragmas that are a bit similar; look in
