Remove save_inferior_ptid
This removes save_inferior_ptid, a cleanup function, in favor of scoped_restore. This also fixes a possible (it seems unlikely that it could happen in practice) memory leak -- save_inferior_ptid should have used make_cleanup_dtor, because it allocated memory. I tested this on the buildbot. However, there are two caveats to this. First, sometimes it seems I misread the results. Second, I think this patch touches some platforms that can't be tested by the buildbot. So, extra care seems warranted. ChangeLog 2017-08-18 Tom Tromey <tom@tromey.com> Pedro Alves <palves@redhat.com> * spu-multiarch.c (parse_spufs_run): Use scoped_restore. * sol-thread.c (sol_thread_resume, sol_thread_wait) (sol_thread_xfer_partial, rw_common): Use scoped_restore. * procfs.c (procfs_do_thread_registers): Use scoped_restore. * proc-service.c (ps_xfer_memory): Use scoped_restore. * linux-tdep.c (linux_corefile_thread): Remove a cleanup. (linux_get_siginfo_data): Add "thread" argument.
