<​https://webkit.org/b/119833> Concurrent compilation thread should not trigger WriteBarriers

Reviewed by Oliver Hunt.

The concurrent compilation thread should interact minimally with the Heap, including not
triggering WriteBarriers. This is a prerequisite for generational GC.
