Since the x64 backend currently doesn't emit ABI compliant code, it is
not possible to unwind the stack. During Win64 SEH this will cause the
exception handling to abort, and not even call the unhandled exception
handler. Embedders are advised to install a custom unwind callback using
RtlInstallFunctionTableCallback for the entire code range to catch
unwind attempts for exception handling.

The thread local key for assert scopes can be lazily initialized and

   The test mjsunit/regress/regress-sqrt compares the result of Math.sqrt function
   when using full-compiler and crankshaft compiler seperately. But according to
   glibc bug fixing(https://sourceware.org/bugzilla/show_bug.cgi?id=14032). The
   glibc implementation of std::sqrt() (It is invoked in the generated code when
   full-compiler is used.) will change since glibc 2.19.

   In order to keep consistence of Math.sqrt translation in crankshaft compiler
   and the pass of mjsunit/regress/regress-sqrt. we translate the Math.sqrt func
   by calling the runtime function.

The blink may pass a very long string to v8
for making a handle to it. v8 has max string length
limit and creates exception. But NewExternal code does not
check that the handle is null and crashes the renderer.

With the fix the js code receives the exception.
