This changes test_property_syntax_errors.html in the following ways:
(1) removes the "known failures" handling, since there aren't any
(2) changes it to test syntax errors in both quirks mode and standards
mode, instead of only in standards mode
(3) uses a (new) quirks_values mechanism to property_database.js to
test cases that should be invalid in standards mode but accepted in
quirks mode
