This removes a lot of boilerplate `Print` functions in favor of a CRTP-based approach that uses a `Label` field as an automatic prefix. This `Label` is also made available for other purposes, particularly `IdKind` crash messages in this change. In particular, for `RequireIdKind` in node_stack.h from using numeric IdKinds (e.g., 5 and 24) to something that will print `IdKind(<label>)` (this came up recently on #toolchain). While I'm in here, also doing some other tinkering: - Moving operators to be `friend` members, to reduce the extra templating now that the base types are templated. - Adjusts IntId diagnostics from `int [...]` to `int(...)` for consistency with other id printing. - Changes InstBlockId's label from "block" to "inst_block", since we have multiple blocks now. - Fixes StructTypeFieldsId to use "struct_type_fields" instead of "type_block" (from `TypeBlockId`) - Does some more adjustments from camelCase to snake_case for consistency
