signals: set_restore_sigmask TIF_SIGPENDING
Set TIF_SIGPENDING in set_restore_sigmask. This lets arch code take TIF_RESTORE_SIGMASK out of the set of bits that will be noticed on return to user mode. On some machines those bits are scarce, and we can free this unneeded one up for other uses. It is probably the case that TIF_SIGPENDING is always set anyway everywhere set_restore_sigmask() is used. But this is some cheap paranoia in case there is an arcane case where it might not be.
