This commit adds and adapts the official JSON5 parser tests.
`test/todo/json5.js` should be moved to `test/node` as soon as we fix
all the failures.

+# Parse Test Cases for JSON5
+
+The test cases' file extension signals the expected behavior:
+
+- Valid JSON should remain valid JSON5. These cases have a `.json` extension
+  and are tested via `JSON.parse()`.
+
+- JSON5's new features should remain valid ES5. These cases have a `.json5`
+  extension are tested via `eval()`.
+
+- Valid ES5 that's explicitly disallowed by JSON5 is also invalid JSON. These
+  cases have a `.js` extension and are expected to fail.
+
+- Invalid ES5 should remain invalid JSON5. These cases have a `.txt` extension
+  and are expected to fail.
+
+This should cover all our bases. Most of the cases are unit tests for each
+supported data type, but aggregate test cases are welcome, too.
