htl: Reimplement GSCOPE
This is a new implementation of GSCOPE which largely mirrors its NPTL counterpart. Same as in NPTL, instead of a global flag shared between threads, there is now a per-thread GSCOPE flag stored in each thread's TCB. This makes entering and exiting a GSCOPE faster at the expense of making THREAD_GSCOPE_WAIT () slower. The largest win is the elimination of many redundant gsync_wake () RPC calls; previously, even simplest programs would make dozens of fully redundant gsync_wake () calls.
