RFR: 8352893: C2: OrL/INode::add_ring optimize (x | -1) to -1 [v3]

[Manuel Hässig]

> # Issue Summary
> 
> The `add_ring()` implementations of `OrINode` and `OrLNode` are missing the optimization that an or with a value where all bits are ones (since we have signed integers in this case `~0 == -1`) will always yield all zeroes.
> 
> # Changes
> 
> This PR makes the following straight forward changes:
>  - `Or(I|L)Node::add_ring()` returns `-1` if one of the two inputs is `-1`.
>  - Add `Or(I|L)` nodes to the IR framework.
>  - Add a regression IR test for the implemented optimization.
> 
> # Testing
> 
> - [Github Actions](https://github.com/mhaessig/jdk/actions/runs/14110978686)
> - Ran tier1 through tier3 and Oracle internal testing
