Auto merge of #5929 - dwijnand:remove-hamcrest, r=alexcrichton

Replace lots of hamcrest's assert_that with a builder style

Refs #5742

I've been thinking of possible solutions to close out #5742, so I'm submitting this for early feedback.

@alexcrichton what do you think? If you like the look of this I'll apply it across the suite.
