I don't understand this code in JITStubs::cti_op_call_arityCheck():
ASSERT(argCount != newCodeBlock->m_numParameters);
It's ensuring that the argument count does not equal the number of
parameters expected by the newCodeBlock. I could understand if it
was ensuring the argCount was the same, but why different?
This slower code path must only be used when the number of parameters
is not equal. If it was used when the number of parameters was equal,
it would be a performance bug.
