Message:

Fix testkjs in 64-bit.

When built for 64-bit the TCMalloc spin lock uses pthread mutexes rather than a custom spin lock
implemented in assembly. If we fail to initialize the pthread mutex, attempts to lock or unlock
it will fail and trigger a call to abort.

Reviewed by Darin.

• wtf/FastMalloc.cpp: Initialize the spin lock so that we can later lock and unlock it.
• wtf/TCSpinLock.h: Add an Init method to the optimised spin lock.
