Josh Bleecher Snyder	518248cfad	cmd/compilebench: add -pkg flag to compile a single package ... Sometimes, as with CL 41493, or when investigating a reported issue, there's a package of interest that is not part of the standard compilebench suite. Add a -pkg flag to allow easy access to the compilebench set of goodies (allocs, object file stats) without having to edit and reinstall compilebench itself, which is what I have been doing.
