This was previously discussed at https://discord.com/channels/655572317891461132/655578254970716160/1209975051588210729. I'm initiating this mainly because we typically use "id" suffixes to indicate an `IdBase` being passed around and the non-id suffix of `parse_node` suggests at it carrying more data than it actually does. There used to be more reason for avoiding `node_id` because `SemIR::InstId` used to be named `NodeId`, but that's no longer necessary. As a consequence, I'd like to rename `parse_node` to more precisely reflect its type. In full, this is doing: ``` parse_node_kind -> node_kind parse_node -> node_id ParseNodeCategory -> NodeCategory ParseNodeKind -> NodeKind ParseNode -> NodeId ``` This is primarily in check and sem_ir, but with some `parse_node_kind` references in parse too. Pluralization is consistent with name forms on both sides, so that wasn't part of my replacements.
