Adding case to computed property

Array.prototype.sort and %TypedArray%.prototype.sort should throw on a non-undefined non-function (#1059)

Per https://github.com/tc39/ecma262/pull/785/

A recent commit introduced a document that enumerated acceptable values
for the test "features" metadata tag. However, this list was incomplete,
and maintaining it placed extra burden on the project owners.

Restructure the document into a machine-readable format. Add entries for
all previously-omitted values. Add in-line documentation with
recommendations for maintenance of the file. Extend the project's
linting tool to validate tests according to the document's contents.

Remove src/dstr-assignment/default/for-await-of.template (invalid)

Remove more unnecessary tests

Update TR 104

These tests are not helpful for their respective APIs being tested.

They don't add any coverage for the built-in apis and basically check
behaviors that might conflict with a implementation defined global.

Remove unnecessary tests

These tests are not adding any coverage to the respective API they
should be covering.

There are other files checking cases for array-like objects, and
playing this with the global might cause issues and unnexpected
behavior on specific environments like browsers.

Thanks to @anba for spotting this: https://github.com/tc39/test262/pull/1014/files/4843f049fafb6cdd61e3be011e3701cc94a9fe46#r116528031
