Relocate and refactor tests

The tests for the parsing of `for/in` loops were expressed using eval.
This made the tests more complex than necessary and also prevented the
tests from providing value to ECMAScript parsers.

Remove the use of eval and instead express the expectations with literal
source text. Move the tests to the `for-in` directory to better reflect
the grammar production that they test.
