Reviewed by Filip Pizlo.

* Scripts/jsc-stress-test-helpers/check-mozilla-failure: Removed. Was just a ruby reimplementation
of grep -i -q
* Scripts/run-javascriptcore-tests: Pass through the --tarball flag.
* Scripts/run-jsc-stress-tests: Changed to create a bundle of tests inside the results directory.
We now also copy whatever VM was specified, along with its associated framework, into this directory.
All of the generated scripts now are completely relative within the results directory. This allows
run-jsc-stress-tests to execute a bundle from anywhere. Also added a --tarball flag which creates a
tarball of the generated results directory. Also refactored several portions of the script into
separate functions to make it easier to run them conditionally depending on which mode we're running in.
