Regenerated all out.ll files after reinstalling llgen to fix TestFromTestrt and TestFromTestgo test failures.
Updated files:
- cl/_testgo/equal/out.ll
- cl/_testrt/asmfull/out.ll
- cl/_testrt/makemap/out.ll
- cl/_testrt/tpmap/out.ll
The changes correctly update interface PkgPath from specific package paths to empty strings (zeroinitializer) for interfaces with only exported methods, which aligns with the fix in PR #1380 for issue #1370.

Reverted two unnecessary formatting changes based on code review:
- ssa/interface.go: Restored single-line format for val function
- ssa/abitype.go: Moved pkg variable declaration back to original position
These changes don't affect functionality, just code formatting.

Based on meeting discussion, this commit reverts the previous approach
of extracting PkgPath from interface methods. Instead, anonymous
interfaces now use an empty PkgPath string, and the runtime's methods()
function handles empty PkgPath by returning all methods.
Changes:
- Reverted unsafeInterface() to remove originType parameter
- Set anonymous interface PkgPath to empty string in abitype.go:202
- Added early return in methods() in z_face.go for empty PkgPath
- All call sites of unsafeInterface() updated to pass rawIntf directly
This approach is cleaner because anonymous interfaces don't belong to
any package, and the compiler already guarantees safety for cross-package
private method access.

Fixes#1370 - Segmentation Fault When Calling Interface Private Methods Cross-Package
This commit fixes a critical bug where interface metadata's PkgPath was incorrectly
set when converting concrete type pointers to interfaces with private methods across
package boundaries.
Problem:
- When a concrete type pointer was converted to an interface with private methods
in a package different from the interface definition package, the compiler
incorrectly set the interface metadata's PkgPath to the current compilation
package instead of the interface definition package
- This caused the runtime to only fill exported methods in the itab, leaving
private method slots as NULL (0x0), resulting in segmentation faults
Solution:
- Modified abiInterfaceOf() in ssa/abitype.go to extract the package path from
the interface's private methods (if any)
- Use that package path instead of the current compilation package path
- Fall back to current package path only if all methods are exported
Changes:
- ssa/abitype.go: Use abi.PathOf() to get correct package path
- ssa/interface.go: Refactor to simplify interface type handling
- Added comprehensive test cases and demos for go/types, go/token, and go/ast
- Updated all test outputs to reflect correct interface metadata generation
This fix resolves segmentation faults when using Go standard library interfaces
and user-defined interfaces with private methods across package boundaries.

- Fix line 67: Change unused variable 'n' to blank identifier '_'
- Fix line 102: Correct WriteByte call to expect only error return value
(WriteByte returns only error, not (int, error))
These fixes resolve the compilation errors reported by the CI.

- Add tests for all major hash/maphash public APIs:
* Hash basics (WriteString, Sum64, Reset)
* MakeSeed and SetSeed functionality
* Write methods (Write, WriteByte, WriteString)
* Bytes and String convenience functions
- Use panic() for unexpected errors instead of silent failures
- Add proper error checking and validation
- Document Comparable/WriteComparable limitations in overlay
Note: Comparable() and WriteComparable() are not yet supported and will
panic with 'intrinsic' error as they require runtime intrinsic support.

Implement randUint64() directly in the maphash overlay to ensure compatibility
across Go versions. Go 1.21's randUint64() calls runtime.fastrand64, while
Go 1.22+ calls runtime.rand. The wrapper function bridges to llgo's fastrand64
implementation, avoiding undefined symbol errors on Go 1.21.

The llgo:skipall directive was preventing fallback to the standard library,
causing undefined symbol errors for functions like WriteString, MakeSeed, etc.
The overlay now only defines the two linkname functions, allowing typepatch
to handle the rest.
