[webkit-dev] cti_op_call_ArityCheck question

[Gavin Barraclough]

We check in JIT code for cases where arity match, and skip the call to  
the stub; this function is only called if there is a mismatch to be  
resolved.  The function would probably be better named something like  
'cti_op_call_handleArityMismatch'.

cheers,
G.
