    PR17525 - breakpoint commands not executed when program run from -x script

    Executing a gdb script that runs the inferior (from the command line
    with -x), and has it hit breakpoints with breakpoint commands that
    themselves run the target, is currently broken on async targets
    (Linux, remote).

    While we're executing a command list or a script, we force the
    interpreter to be sync, which results in some functions nesting an
    event loop and waiting for the target to stop, instead of returning
    immediately and having the top level event loop handle the stop.

    The issue with this bug is simply that bpstat_do_actions misses
    checking whether the interpreter is sync.  When we get here, in the
    case of executing a script (or, when the interpreter is sync), the
    program has already advanced to the next breakpoint, through
    maybe_wait_sync_command_done.  We need to process its breakpoints
    immediately, just like with a sync target.

    Tested on x86_64 Fedora 20.
