Refactor, reorganize, and extend tests for line terminators

Previous commits restructured the tests for line terminators and made
coverage gaps more apparent. Introduce new files to improve coverage.

The tests for the parsing of line terminators 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. Rename the files to make each test's purpose more clear.

The behavior asserted by the removed tests is covered by other files.
