In c6d7e80ec4 this test was converted from hand written to autogenerated,
during which the relevant metadata CHECKs were dropped. In D85172 the intention
of the CHECK lines is to ensure that for two dbg.declares with different
inlining scopes, attached to the same alloca, two sets of dbg.values will be
generated with the same set of inlining scopes. Without metadata checks, a
single DILocation can match the !dbg CHECKs.
