Subject: [PATCH] Remove duplicated constructor tests

A number of tests were found to be duplicative based on an analysis of
file contents (included below). Eliminate the duplication by removing
the version of each test with less precise metadata. In cases where this
removal could technically be considered a reduction in coverage,
preserve the verification of additional semantics in the remaining test.

    $ git grep -El 'new\s+\w+.prototype' | sed 's/[^\/]\+$//g' | sort | uniq -c | grep -vE '^\s+1 ' | awk '{print $2}' | xargs grep -Elr 'new\s+\w+.prototype'
