Update for new eval restrictions on super (#781)

A recent change to the specification [1] introduces parse-time errors
for certain usages of `super` within eval code. Modify all tests that
are affected by this change:

- Update the test bodies to accurately enforce the new semantics
- Rename files to better reflect the section of the specification that
  they enforce
- Update test meta-data
  - Change the `esid` meta-data to reflect the location of the relevant
    specification text
  - Remove the `es6id` meta-data as the behavior is no longer relatable
    to that specification
  - Introduce the `features` meta-data in cases where the test file's
    new location no longer reflects all required language features
