Summary: In r367234 we introduced a central place to hold the set up commands for the various ways we have of launching lldb. However, a number of commands still remained outside of that. This patch moves the remaining set up commands into this function, which allows us to remove manual clang module path setting code in TestBatchMode. One unfortunate victim of this approach is TestSTTYBeforeAndAfter which, due to how it launches lldb (pexpect->expect->lldb), fails get the quoting right. It would be possible to fix the quoting there, it would be a bit icky, and none of the commands in this list are really relevant for what this test is doing, so I just remove the commands outright.
