I checked in a new tool, primarily useful for debugging. Given a module and a function name, it extracts just the specified function from the module, with a minimum of related cruft (global variables, function prototypes, etc). This is useful because often something will die (for example SCCP miscompiles one function of a large benchmark), and so you want to just cut the testcase down to the one function that is being a problem. In this case, 'extract' eliminates all of the extraneous global variables, type information, and functions that aren't necessary, giving you something simpler. This is just an FYI, because I've found it useful and thought you guys might as well.
