ed92862522 misc/ios: timeout and continue waiting for getwd
Split out from cl/8024 for clarity and improved approach.

Rarely, "stop reason = breakpoint" does not appear in the lldb stop
text. However the program is ready to proceed. To be a little more
robust about those cases, we wait for two seconds, and if that text
doesn't appear but a prompt does we continue and hope for the best.
Worst case, this results in a harder to read failure message.

7ff6254c50 misc/ios: run lldb commands much more carefully
We now wait until we see the completed prompt from a command before
proceeding. This seems to cut down on a spurious error I have seen
this afternoon.

1fdeb6b58a misc/ios: extra stdout check before run
On one recent job I saw an unexpected SIGSTOP, which I suspect is
simply the job timeout. But the lack of other diagnostics suggests
lldb just didn't see the "run" command.

d460b6e5c6 misc/ios: add go_darwin_arm_exec script
This script is getting very close to complete, and is complex enough
that I'd like to get what's there so far reviewed. With it the builder
is left failing on eight packages. Two of those involve correcting
GOROOT which may need modifications to this script, the others are
either a unix sockets bug I have to hunt down or are caused by lldb
getting stuck on SIGSEGV, a TODO.
