Comment (by bgamari):
I setup a test environment to build just `tests/Utilities.hs`,
`tests/Boilerplater.hs`, and `tests/Tests/Vector.hs` with both GHC 8.3
(13131ce9165b4e5e5193dc381f6f3d021e53792f and 8.0.2. In addition to
building `Tests.Vector` as-is, I also built it enabling each of the
testcases in the `tests` list individually (that is, commenting out all
but one). The result is interesting: While compilation on `master` is
significantly faster than 8.0.2 in the individual cases, it is
significantly slower when all of the testcases are enabled. Clearly there
is something non-linear going on here. I'm on the case.
