I mean having more points in the testing matrix.

Clang check-all is cheaper than running the test-suite, but if we
start moving more tests to the suite, we'll have to run it for more
combinations. For slow targets, that mostly means a new buildbot,
because you want the "fast" check-all to not be impeded by the "slow"
test-suite for every commit.

The "non-trivial" amount is the sole difference in how many machines
you can get to have a reasonable amount of commits in the blame-list
for everything we test, which is trivial on fast x86_64 servers.
