    RISC-V: Rename some variables of vector_block_info[NFC]
    
    1. Remove "m_" prefix as they are not private members.
    2. Rename infos -> local_infos, info -> global_info to clarify their meaning.
    
    Pushed as it is obvious.
    
    gcc/ChangeLog:
    
            * config/riscv/riscv-vsetvl.cc (pre_vsetvl::fuse_local_vsetvl_info): Rename variables.
            (pre_vsetvl::pre_global_vsetvl_info): Ditto.
            (pre_vsetvl::emit_vsetvl): Ditto.
    
    (cherry picked from commit 4fd09aed384df6acb141ee1f319a500c239626a4)
