nbp milestoned Issue #866:

This changes are replacing the iteration over all instructions by an iteration over the last 2 instructions of basic blocks, when basic-blocks feature is enabled.

I am confident this change is likely improving performances. However, until the front-end is completely fixed to generate valid basic blocks, we have no way to check the performances of this code on benchmarks.

I tried running the test suite, but it takes less than a second, which does not give me much confidence.

I think this PR was quite complete at the time, it was only a draft as it depend on the "new" bb.

This looks good to me. @nbp do you have time to rebase this? If not I can take this and rebase it.

This will require a change now that #1363 has been merged, as the feature gate has been removed.

I'm going to work on this after #1365 is merged. I don't this commit will apply at all after then, so I'll probably end up rewriting it and attributing @nbp.
