Commit ID 05513a66410f96959f3a6e70be9aea72425cf7c7
Author Marco Costalba

Only main thread checks time The main change of the patch is that now time check is done only by main thread. In the past, before lazy SMP, we needed all the threds to check for available time because main thread could have been blocked on a split point, now this is no more the case and main thread can do the job alone, greatly simplifying the logic. Verified for regression testing on STC with 7 threads: LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 11895 W: 1741 L: 1608 D: 8546 No functional change. Closes #1152
