Some regression tests which are testing the old jit and are exercising functionality which is both known to be broken and not expected to be fixed in the old jit. To remove these from the regression test output, I've marked them XFAIL (for lit tests) and ifdef'd them out (unit tests). These modifications remove the last long-standing regression test failures from the buildbots (though updating the triple to reflect new ubuntu configuration has temporarily caused some new failures). Tested on x86-64 and ARM Linux.
