> The suspend flag's TLS offset used by JIT agorithms was incorrect after the latest merge of TM.
> As the result every loop iteration BBP algorithm uses slow path.
> This patch 
> 1) Fixes the problem 
> 2) Adds new functionality to TM: the UDATA VMCALL hythread_tls_get_offset(hythread_tls_key_t key)  method.
> 3) Removes jit_private data field from HyThread 
> 3) Fix JIT to always use allocation algorithm for TLS keys, not hardcoded values.
