VectorizeLoop accepts a const Analyzer pointer, while VectorizeRewriter requires a mutable Analyzer to simplify loop extents. Passing the pointer directly fails C++ compilation.

Clone the analyzer before constructing the rewriter, preserving the caller's analysis context while providing a mutable copy. This follows the existing approach in GetVectorizeSize.

Related to #3226.

Summary

• VectorizeLoop clones the supplied analyzer before constructing VectorizeRewriter.
• The rewriter uses the mutable clone, preserving the caller’s analysis context.
• Vectorization hint handling and the vectorize_hint == 1 path remain unchanged.

C++ style / lint notes

• The PR changes C++ source. The touched rules in docs/developer_guide/cpp_style.md concern parameter and analyzer usage; the change does not alter a public API.
• CI includes the “C++ API Style Audit (warning only)” step. No audit results were provided.
• No build or test results were provided.

📝 Walkthrough

VectorizeLoop now passes a cloned arithmetic analyzer to VectorizeRewriter. Vectorization hint handling and the vectorize_hint == 1 path remain unchanged.

Changes: Loop vectorization

Layer / File(s)	Summary
Clone the analyzer src/transform/loop_vectorize.cc	VectorizeLoop passes a cloned arithmetic analyzer to VectorizeRewriter instead of passing the caller’s analyzer directly.
