Typerew uses checking operations (e.g. CAR with type checks enabled,

Changed the illegal-arg error handler for primitive procedures to

the compiler assumes that if it calls a primitive just to raise an
error then teh primitive will not return. This assumption allows type
inference to eliminate furthur checks.
In order to stop the debugger returning a value, the primitive should
be called `indirectly' via another compiler procedure which refuses to
return. I.e instead of compiling the error CAR operation as
INVOKE:PRIMITIVE
(#[primitive-procedure car] x)
call it like this:
(signal-primitive-error '#[primitive-procedure car] x)
