Git commit e1784a875479f2bb3fd139c7fff75393a3b91dc5 by Momchil Velikov on 15/07/2026 at 15:57..
[GVN] Remove the "private" `llvm::gvn` namespace (NFC)

Move `AvailableValue` and `AvailableValueInBlock` into GVNPass, similar
to other helper types.

Retain `llvm::gvn::GVNLegacyPass` as just `llvm::GVNLegacyPass` -
"legacy" is already a sufficent hint and it is not going to become more
"private" by stacking "gvn" prefixes to the name.

Ideally, `GVNLegacyPass` should be defined in an anonymous namespace, but
that is not possible because it is declared as a friend of GVNPass.

[GVN] Remove unused debug helper (NFC)

The `GVNPass::dump` method is not used anywhere. Moreover, there's
no `GVNPass` state that corresponds to its parameter type. Even if a
`GVNPass::dump` method could be useful, this one wasn't it.
