- tldr
- The RISC-V macro fusion logic was moved to riscv-fusion.cc to prevent riscv.cc from becoming too large.

The RISC-V backend’s macro fusion logic, specifically the riscv_macro_fusion_pair_p function, was moved from riscv.cc to a new file, riscv-fusion.cc. This change aims to improve code organization and maintainability as more fusion cases are added. New tests were added to verify existing fusion cases tied to specific microarchitecture tunings.
