Adds **class method declarations** and a **direct call op**, wires them into the importer, and supports implicit `this`, inherited property access, and upcasting. - **New ops** - `moore.class.methoddecl`: declare methods inside `classdecl` (FunctionType). - `moore.class.call`: direct (non-virtual) method call; verifies callee, arity, and types. - **Importer** - Lowers `t.m(...)` and unqualified `m(...)` (inside methods) to `class.call`. - Adds implicit `%this : !moore.class<@C>` as first block arg for methods. - Performs **implicit upcast** of the receiver when needed. - Resolves class properties via `class.property_ref` (now also for implicit `this`). - Clearer diag: prints SV type for unsupported member-access bases. - **Lowering plumbing** - `declareFunction` split into `declareCallableImpl` to share logic; supports methods (qualified name `@"Pkg::Class"::method`). - Tracks `currentThisRef` in `Context` for implicit `this` in expressions. - `ClassDeclVisitor` emits `class.methoddecl` in source order after lowering the method body. - **Verifiers / build** - `ClassDeclOp` verifier accepts `class.methoddecl`. - `ClassCallOp` verifier checks symbol -> function, FunctionType, operand types. - Includes/linkage for call interfaces (`MooreOps.h`, CMake). - **Tests** - `classes.sv`: calls on concrete classes, inherited property access through upcast, and method decls reflected in IR.
