    RISC-V: Remove unit-stride store from ta attribute
    
    Since store instructions doesn't care about tail policy, we remove
    vste from "ta" attribute. Hence, we could have more fusion chances
    and better optimization.
    
    gcc/ChangeLog:
    
            * config/riscv/vector.md: Remove vste.
