std: update `std.builtin.Type` fields to follow naming conventions The compiler actually doesn't need any functional changes for this: Sema does reification based on the tag indices of `std.builtin.Type` already! So, no zig1.wasm update is necessary. This change is necessary to disallow name clashes between fields and decls on a type, which is a prerequisite of #9938. 2024-08-28 02:35:53 +01:00			`const fields = @typeInfo(T).@"struct".fields;`
