/// This is a simple utility pass that verifies the ownership of all SILValue in
/// a module with a special flag set that causes the verifier to emit textual
/// errors instead of asserting. This is done one function at a time so that we
/// can number the errors as we emit them so in FileCheck tests, we can be 100%
/// sure we exactly matched the number of errors.
