ART can't create more than 8k threads during the worktime

ART uses LDT to point to the Java Thread structure. This structure
can holds up to 8k pointers, so we can have 8k threads simultaneously.
But the current implementation does not free slots for the finished threads.
This means there cannot be more than 8k threads created during the whole
life cycle.
This patch implements the LDT slots freeing mechanism.
