        This patch adds defaultNoEagerRun to all the tests

        The reason is that an OSR Exit can be unrelated to the tested

        Import Chakra tests to JSC
        https://bugs.webkit.org/show_bug.cgi?id=154697

        Reviewed by Saam Barati.

        Added Chakra tests.  All these tests are under Chakra/test.  This is the same layout
        for tests in the Chakra tree.

        Created a ChakraCore.yaml file to be used with run-jsc-stress-tests.  This file contains
        the tests that are run when the original Chakra runtests.py script is run.  That script
        is the test driver for *nix platforms and does not attempt to run all tests or all
        variations of tests.  The runtest.py driver consults rlexe.xml files in each test
        subdirectory to determine the test to run, the options to pass to the test and how to
        determine pass/fail of the test.  With runtests.py as the start, tests that didn't
        pass directly where either skipped, with a message describing why or through 
        adjustments to the test infrastructure, as described below, where made to pass.
        
        The only modification to the test infrastrucutre are:

         1) Added simple mapping of Chakra expected exception text to JSC expected text in
            test/UnitTestFramework/UnitTestFramework.js.  It would make sense to also
            map some JSC specific exception text to more generic text for the cases where
            that text contains indetifier names or other source specific strings and the
            Chakra equivolent exception texts are generic.  
 
         2) Created JSC specific expected text files where it is clear that the text work
            as expected on JSC but the test output is different.  Typically the differences
            fall into three categories, different exception output, different output from
            toString() of a function, slight numeric differences, and test that rely on
            iteration order.

         3) Stripped the CR's from the CR-LF line terminations of the files.  

        No actual test .js files were modified.

        The test checks Math.random() correctly produces 53bit random values.
        The test can fail by design, but this should be fairly rare.

        However, when introducing, we wrap the `test()` with 1e4 to ensure the FTL compilation, and this
        increases the failure rate. By increasing the MAX in the test, we make the failures much more rare case.

        And we also add getRandomSeed() and setRandomSeed(seed) JSC shell helpers to dump more useful information
        and reproduce the situation easily.

        We should not keep the JavaScript tests inside the Source/JavaScriptCore/ directory.
        https://bugs.webkit.org/show_bug.cgi?id=160372

        Rubber stamped by Geoffrey Garen.

        This patch moves all the JavaScript tests from Source/JavaScriptCore/tests to
        a new top level directory, JSTests. Having the tests in the Source directory
        was both confusing an inconvenient for people that just want to checkout the
        source code of WebKit. Since there is no other obvious place to put all the
        JavaScript tests a new top level directory seemed the most sensible.

        * tests/: Deleted.
