[Attributor] Convert test to opaque pointers (NFC)

[nikic]

Highlighted the relevant differences.

llvm/test/Transforms/Attributor/nocapture-2.ll

169

We get more returned due to missing bitcasts -- expected.

176

We lost dereferenceable_or_null on @scc_A calls -- it's still present on the declaration though, so no real loss of information. Probably not supposed to happen though?

222

dereferenceable_or_null increase to 8 is correct, because we now recognize that we return the argument, which has a dereferenceable_or_null(8) attribute.

Rebase

[nikic]

Rebase over more test changes.

LG, sorry I'm changing tests a lot right now.
