Summary: The "i1" (viz. bool) type does not have a proper equivalent on the "C" size. So, to avoid any ABIs issues, we simply use print_i32 on an i32 value of one or zero for true and false. This has the added advantage that one less function needs to be implemented when porting the runtime support library.
