[JSC] Drop ArityCheckData
​https://bugs.webkit.org/show_bug.cgi?id=178648

Reviewed by Mark Lam.

ArityCheckData is used to return a pair of slotsToAdd and thunkToCall.
However, use of thunkToCall is removed in 64bit environment at r189575.

We remove thunkToCall and align 32bit implementation to 64bit implementation.
Since we no longer need to have the above pair, we can remove ArityCheckData too.
