[JSC] Remove valueProfileLock
https://bugs.webkit.org/show_bug.cgi?id=322701
rdar://185966544
Reviewed by Keith Miller.
ValueProfile collection was taking a lock only on 32bit before, and
valueProfileLock was empty on 64bit. Now 32bit JIT is dropped and we no
longer need to consider about this locking case. This patch removes
valueProfileLock (It was NoLockingNecessaryTag so no effect).
