fourthTier: Add another temp register regT4 to JSInterfaceJIT
​https://bugs.webkit.org/show_bug.cgi?id=117719

Reviewed by Geoffrey Garen.

Made the dedicated bucketCounterRegister to be regT4 and then used regT4 wherever
bucketCounterRegister had been used. Since it is masked whenever it is used and
we are looking for some randomness in the register anyway, we can use it without
any issues.
