Improve test precision

Previously, some tests verified two independent concerns simultaneously:
syntactic validity and runtime completion value. The former is relevant
for ECMAScript runtimes and parsers alike, but the latter is only
observable by runtimes.

Express expectations regarding syntactic validity using literal program
code so they can be used by parsers. Maintain the original tests which
rely on eval in order to preserve coverage for statement completion
values.
