From 0bade020a098334c4241b7c64854d79beaaac950 Mon Sep 17 00:00:00 2001
From: Johnny Chen <johnny.chen@apple.com>

Subject: Add a test script for verifying that the convenience variables:

o lldb.debugger
o lldb.target
o lldb.process
o lldb.thread
o lldb.frame

"just works" when we stop at a breakpoint.
