…tests This not only reduces code duplication already, it also gives us revision parsing for free which we need in upcoming commits. Long term we should probably use newtypes to avoid mixing up zero-based and one-based line numbers. For now, rename var name to `zero_based_line_no` to make things slightly clearer. `check_lines` uses zero-based, but `DirectiveLine` use one-based.
…, `no-SingleUseConsts-mir-pass` To prevent the test from regressing both with and without `SingleUseConsts` MIR pass.

TODO
LineNonewtype to avoid+1magic here and there #150205 once merged so we don't have to add another "+ 1".CC
CC @Zalathar since you might have opinions about that I expose a helper function to reduce duplication
CC @saethlin since this is what we will use for
tests/debuginfo/basic-stepping.rsin #147426 (in the same way I use it intests/debuginfo/macro-stepping.rshere)
