Several new Sputnik tests included:

if (!strict_mode) { throw new SyntaxError('unspecified case'); }

This doesn't work for a few reasons:
1.  'strict_mode' is undefined in the test case exeuction context. That is, the test framework
    does not force the test case into strict mode
2.  The test case code looks like:
	"use strict";
	if (!strict_mode) ...
        ...
    Note that 'strict_mode' is not set before being accessed

Really the metadata for these test cases should have a "@strict" property added to instruct the test
framework *not* to run the test if an implementation doesn't support strict mode.
