Added this check to the linting script and updated tests accordingly.
Prior to this patch, the tests for certain Array prototype methods
incorrectly expected all elements to be "visited" even when a given
property was not present according to HasProperty.
Update the tests to reflect the fact that under such conditions, the
removed element is not visited.
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.

The Resizable ArrayBuffer proposal allows implementations to reject any
resize operation, so the tests must accommodate that possibility.
Mitigate the complexity this entails by minimizing branches and by
deferring assertions to locations with shallow call stacks.
Some tests which include function declarations designed to verify
behavior do not reference those functions. Insert the references
necessary for those functions to serve their intended purpose.
This reverts commit b690cb67be9b487eb10156c03e2c00869e88cc9d, reversing
changes made to 50dd431dffe5cf86e9064a652d6b01dbbe542cf0. This is
necessary because the reverted changeset reduced coverage by an unknown
extent.
Prior to this commit, a test for %TypedArray%.prototype.copyWithin
provided a TypedArray instance as the first argument. That argument that
is interpreted as a number, so in relying on the conversion, the test
verified behavior beyond what it purported to test.
Simplify the test by using the desired number value directly, and extend
the tests for type coercion to cover object values.
