Bug 496923 - Remove all existing test402 tests, as they're a subset of the test262 tests that we'll be piecewise-importing (and the intl402 bits will be in the first imported batch).  r=terrence
Bug 496923 - Skip failing Intl tests that will be in the initial test262 import, and update skips so that the Intl tests won't run when Intl isn't built.  r=terrence

Bug 496923 - Implement a script which clones the test262 repository and copies selected subsets of the tests into the jstests suite so that we can run them on tinderbox.  r=terrence
Bug 496923 - Initial test262 import by subsets.  r=generating-script-was-reviewed
