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.

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

These files were authored to test the effect of the carriage return
character, but that character was not present in the source text.

Insert the character as intended by the authors.

Four tests were documented as asserting the interpretation of line
terminators within multi-line comments, but the source code did not
actually demonstrate this condition.

Introduce new tests that demonstrate the intended functionality and
place them in the correct directory.
