[Ada] Add field "thread-id" in -ada-task-info output

This patch enhances the -ada-task-info command, adding a new
field called "thread-id" in the command output.  This field
provides the ID of the task's corresponding thread (if that
information could not be determined, the field is omitted).

This field is useful in the context of GDB/MI users, because
it allows a quick translation from Ada task to thread, and
thus easy use of all the commands that take a --thread argument.

command.

This new command returns an array, with each row corresponding

thread-specific breakpoints not saved properly by save-breakpoint

Initially, I noticed that the save command was often missing
new lines in the file that it generated.  For instance, consider:

        % gdb save-bp
        (gdb) b break_me
        (gdb) b save-bp.c:27
        (gdb) save breakpoints bps

The contents of the bps file would be:

        % cat bps
        break break_mebreak save-bp.c:27

Looking further into the problem, I realized that the missing newlines
are just a consequence of a missing call to print_recreate_thread.
After having generated the breakpoint location in the break command,
we cannot put a new line until we have looked at whether we need to
add a 'thread NUM' argument.

        * breakpoint.c (bkpt_print_recreate): Add call to

sim: bfin: use store buffer for VIT_MAX insns

The VIT_MAX insns can be used in parallel, so we need to use the store
buffer so we don't clobber the output register before we get a chance
to do a memory store with it.
