Refactor LT tests for parsers: token delimiters

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.
