Boolean8 is defined as an alias for Boolean in the RTL, so it won't 
help. The only ways I can think of to fix this are to either add a new 
ObjCBool type to the compiler (or make Pasbool8 a built-in type that is 
different from Boolean, which amounts to the same thing), or to remove 
the optimization for passing boolean types that's specified in the 
x86-64 ABI.
