lib/test_bitmap.c: add optimisation tests
Patch series "Bitmap optimisations", v2. These three bitmap patches use more efficient specialisations when the compiler can figure out that it's safe to do so. Thanks to Rasmus's eagle eyes, a nasty bug in v1 was avoided, and I've added a test case which would have caught it. This patch (of 4): This version of the test is actually a no-op; the next patch will enable it.
