t3432 had several stress tests for can_fast_forward(), whose intent was
to ensure we were using the optimization of just fast forwarding when
possible.  However, these tests verified that fast forwards had happened
based on the output that rebase printed to the terminal.  We can instead
test more directly that we actually fast-forwarded by checking the
reflog, which also has the side effect of making the tests applicable
for the merge/interactive backend.

This change does lose the distinction between "noop" and "noop-force",
but as stated in commit c9efc216830f ("t3432: test for --no-ff's
interaction with fast-forward", 2019-08-27) which introduced that
distinction: "These tests aren't supposed to endorse the status quo,
just test for what we're currently doing.".

This change does not actually run these tests with the merge/interactive
backend; instead this is just a preparatory commit.  A subsequent commit
which fixes can_fast_forward() to work with that backend will then also
change t3432 to add tests of that backend as well.
