<pre>Need ability to fuzz exception throwing
https://bugs.webkit.org/show_bug.cgi?id=134945
<rdar://problem/17722027>
Reviewed by Sam Weinig.
Source/JavaScriptCore:
Adds the ability to instrument exception checks, and to force some random
exception check to artificially throw an exception. Also adds new tests that
are suitable for testing this. Note that this is closely tied to the Tools
directory changes that are also part of this changeset.
This also fixes an activation tear-off bug that arises if we ever throw an
exception from operationOptimize, or if due to some other bug it's only due
to the operationOptimize exception check that we realize that there is an
exception to be thrown.

Tools:
Adds a new script, js-exception-fuzz, which will run some jsc command-line using
exception fuzzing. This means that we will force exceptions to be thrown in random
places to see how the engine reacts. This is now integrated with the various test
drivers, so run-javascriptcore-tests will run some exception fuzzing tests by
default.
* Scripts/jsc-stress-test-helpers/js-exception-fuzz: Added.

+ Need ability to fuzz exception throwing
+ https://bugs.webkit.org/show_bug.cgi?id=134945
+ <rdar://problem/17722027>
+
+ Reviewed by Sam Weinig.
+
+ Adds a new script, js-exception-fuzz, which will run some jsc command-line using
+ exception fuzzing. This means that we will force exceptions to be thrown in random
+ places to see how the engine reacts. This is now integrated with the various test
+ drivers, so run-javascriptcore-tests will run some exception fuzzing tests by
+ default.
