2017-07-03test: remove common.noopRich Trott
This change removes `common.noop` from the Node.js internal testing common module. Over the last few weeks, I've grown to dislike the `common.noop` abstraction. First, new (and experienced) contributors are unaware of it and so it results in a large number of low-value nits on PRs. It also increases the number of things newcomers and infrequent contributors have to be aware of to be effective on the project. Second, it is confusing. Is it a singleton/property or a getter? Which should be expected? This can lead to subtle and hard-to-find bugs. (To my knowledge, none have landed on master. But I also think it's only a matter of time.) Third, the abstraction is low-value in my opinion. What does it really get us? A case could me made that it is without value at all. Lastly, and this is minor, but the abstraction is wordier than not using the abstraction. `common.noop` doesn't save anything over `() => {}`. So, I propose removing it.

2015-12-26test: remove unnecessary assignmentsRich Trott
common.js needs to be loaded in all tests so that there is checking for variable leaks and possibly other things. However, it does not need to be assigned to a variable if nothing in common.js is referred to elsewhere in the test.
