refactor(ssa): rename namedIntf to originType and simplify interface type handling

- Renamed parameter from `namedIntf` to `originType` for clarity
- Removed redundant nil check since `b.abiType()` can handle both Named and Interface types
- Simplified logic by always passing the origin type directly to `b.abiType()`

 **Important:** The `LLGO_ROOT` environment variable must be set to the repository root when running llgo commands during development.
 
-### Update out.ll files after modifying compiler IR generation
-
-**CRITICAL:** When you modify the compiler's IR generation logic (especially in `ssa/` or `cl/` packages), you MUST update all out.ll test files under the `cl/` directory.
-
-#### Understanding out.ll files
-
-The `out.ll` files under the `cl/` directory are comparison IR files that serve as reference outputs for the test suite:
-- They are generated by `llgen` from the corresponding `in.go` files in the same directory
-- They reflect the current compiler's LLVM IR representation of the Go source code
-- They are used by tests to verify that the compiler generates correct and consistent IR output
-
-#### Required steps after modifying IR generation logic
-
-1. **Reinstall the tools** to apply your compiler changes:
-   ```bash
-   go install -v ./chore/gentests
-   go install -v ./chore/llgen
-   ```
-
-2. **Regenerate out.ll files**:
-   
-   **For batch updates (recommended)** - Use `gentests` to regenerate all test files:
-   ```bash
-   gentests
-   ```
-   This will automatically regenerate all out.ll files in these directories:
-   - `cl/_testlibc`
-   - `cl/_testlibgo`
-   - `cl/_testrt`
-   - `cl/_testgo`
-   - `cl/_testpy`
-   - `cl/_testdata`
-   
-   **For individual test inspection** - Use `llgen` to regenerate specific test directories:
-   ```bash
-   llgen cl/_testgo/interface
-   llgen cl/_testrt/tpmethod
-   ```
-
-3. **Verify the changes** make sense by reviewing the diff in the out.ll files
-
-4. **Commit the updated out.ll files** along with your compiler changes
-
-#### Why this matters
-
-This process ensures that:
-- The test suite reflects the current compiler behavior
-- Changes to IR generation are properly documented and reviewed
-- Future regressions can be detected by comparing against the reference output
-
 ## Code Quality
 
 Before submitting any code updates, you must run the following formatting and validation commands:

 ### Defer
 
-LLGo now supports `defer` within loops, matching Go's semantics of executing defers in LIFO order for every iteration. The usual caveat from Go still applies: be mindful of loop-heavy defer usage because it allocates per iteration.
+LLGo `defer` does not support usage in loops. This is not a bug but a feature, because we think that using `defer` in a loop is a very unrecommended practice.

-# Defer Loop GC Integration
-
-## Background
-
-`defer` chains are stored in a per-thread TLS slot so that unwind paths can locate the active `*runtime.Defer`. With the default allocator (`AllocU`) backed by Boehm GC (bdwgc), those TLS-resident pointers were invisible to the collector. In stress scenarios—e.g. `TestDeferLoopStress` with 1,000,000 defers—the collector reclaimed the defer nodes, leaving dangling pointers and causing crashes inside the deferred closures.
-
-Prior experiments (`test-defer-dont-free` branch) confirmed the crash disappeared when allocations bypassed GC (plain `malloc` without `free`), pointing to a root-registration gap rather than logical corruption.
-
-## Solution Overview
-
-1. **GC-aware TLS slot helper** *(from PR [#1347](https://github.com/goplus/llgo/pull/1347))*
-   - Added `runtime/internal/clite/tls`, which exposes `tls.Alloc` to create per-thread storage that is automatically registered as a Boehm GC root.
-   - `SetThreadDefer` delegates to this helper so every thread reuses the same GC-safe slot without bespoke plumbing.
-   - The package handles TLS key creation, root registration/removal, and invokes an optional destructor when a thread exits.
-
-2. **SSA codegen synchronization**
-   - `ssa/eh.go` now calls `runtime.SetThreadDefer` whenever it updates the TLS pointer (on first allocation and when restoring the previous link during unwind).
-   - Defer argument nodes and the `runtime.Defer` struct itself are allocated with `aggregateAllocU`, ensuring new memory comes from GC-managed heaps, and nodes are released via `runtime.FreeDeferNode`.
-
-3. **Non-GC builds**
-   - The `tls` helper falls back to a malloc-backed TLS slot without GC registration, while `FreeDeferNode` continues to release nodes via `c.Free` when building with `-tags nogc`.
-
-## Testing
-
-Run the stress and regression suites to validate the integration:
-
-```sh
-./llgo.sh test ./test -run TestDeferLoopStress
-./llgo.sh test ./test
-```
-
-The updated `TestDeferLoopStress` now asserts 1,000,000 loop defers execute without failure, catching regressions in GC root tracking.
