tile: support CONTEXT_TRACKING and thus NOHZ_FULL
Add the TIF_NOHZ flag appropriately.
Add call to user_exit() on entry to do_work_pending() and on entry
to syscalls via do_syscall_trace_enter(), and also the top of
do_syscall_trace_exit() just because it's done in x86.
Add call to user_enter() at the bottom of do_work_pending() once we
have no more work to do before returning to userspace.
Wrap all the trap code in exception_enter() / exception_exit().
