Add ThreadSpecific for ENABLE(SINGLE_THREADED)
​https://bugs.webkit.org/show_bug.cgi?id=33878

Implement ThreadSpecific with a simple getter/setter
when ENABLE(SINGLE_THREADED) is true.

Due to the change in ​https://bugs.webkit.org/show_bug.cgi?id=33236,
an implementation of ThreadSpecific must be available to build WebKit.
This causes a build failure for platforms without a proper
ThreadSpecific implementation.
