Ignore output data that's not relevant for this test.

The previous code expects output like this:
```
define hidden swiftcc i8* @"$s6SR82094test10ObjectiveC8SelectorVyF"() #0 {
```

But in certain build modes, we get extra debug information that looks like this:
```
define hidden swiftcc i8* @"$s6SR82094test10ObjectiveC8SelectorVyF"() #0 !dbg !47 {
```

I stumbled over this while running tests with a variety of different
options.
