Some optimization passes _improve_ compile times [1]. So we want to run some passes even with `-Copt-level=0`. That means that some of the lines in the test can be optimized away. To make regression testing more robust, we also want to run the test with such passes disabled. The solution is to use two revisions. One with default `-Copt-level=0` passes, and one "even less optimized", with enough optimization passes disabled to keep the maximum number of lines steppable.

//! This tests that `next` skips over macro invocations correctly.

//! The `#locN` markers have no meaning for compiletest, we include them just
