literal-compare-order complains about two literal values being in the wrong order

[Krinkle]

If I understand our code correctly, it is currently limited to literal primitives in terms of recognising "literal" values, so when both values are literals but one is using an array or object, it is (imho wrongly) expressing a warning to swap them around.

	assert.equal( "foo", "foo" );
	assert.equal( "foo", [ "foo" ] );
	assert.equal( "foo", { toString: function() { return "foo"; } } );
	assert.equal( 0, [ 0 ] );

   74:16  error  Expected value "foo" should be specified after actual value [ "foo" ]                                   qunit/literal-compare-order
