1; Test the "-use-source-filename-for-promoted-locals" flag.

8; This module will import b() which should cause the copy of foo and baz from
9; that module (%t1.bc) to be imported. Check that the imported reference's
10; promoted name matches the imported copy. We check for a specific name,
11; because the result of the "-use-source-filename-for-promoted-locals" flag
12; should be deterministic.
