Comment (by mrkkrp):

 Sorry, for throwing it here without sufficient explanations. Here are some
 clarifications:

 https://mail.haskell.org/pipermail/ghc-devops-group/2018-April/000182.html

 And a blog post that describes everything in details is coming.

 If the sum of succeeding/failing test suites is decreases this indicates
 that some test suites failed to build. Hashes are GHC commit hashes on
 master branch.
