There is no _throws_ keyword in ECMACcript262 period.

In fact test262 uses it as identifier preventing any tests to run
if it was keyword.
Add script to run test262 - official TC39 ECMAScript v5.1 test suite.
Add old sputnik testsuite (being ECMAScript V3 mostly).
Use timeout to avoid hanging in test-262.
