This is the subset of incremental tests that should continue to use `bpass` even after `cpass` is supported, because they (presumably) involve codegen.

// This test is almost identical to `cgu_invalided_via_import`, except that

// the two versions of `inline_fn` are identical. Neither version of `inlined_fn`
|

// ends up with any spans in its LLVM bitecode, so LLVM is able to skip
