gdb: Eliminate the 'stop_pc' global
In my multi-target work, I need to add a few more
scoped_restore_current_thread and switch_to_thread calls in some
places, and in some lower-level places I was fighting against the fact
that switch_to_thread reads/refreshes the stop_pc global.
Instead of piling on workarounds, let's just finally eliminate the
stop_pc global. We already have the per-thread
thread_info->suspend.stop_pc field, so it's mainly a matter of using
that more/instead.
gdb/ChangeLog:

comments.
(switch_to_thread_no_regs): Adjust comment.
* infcmd.c (stop_pc): Delete.
(post_create_inferior, info_program_command): Replace references
