    RISC-V: Reset the length to the default of 4 for FP comparisons
    
    The default length for floating-point compare operations is overridden
    to 8, however the FEQ.fmt, FLT.fmt, FLE.fmt machine instructions and
    FGE.fmt, FGT.fmt assembly idioms the relevant RTL insns produce are all
    4 bytes long each.  And all the floating-point compare RTL insns that
    produce multiple machine instructions explicitly set their lengths.
    
    Remove the override then, letting the default of 4 apply for the single
    instruction case.
    
            gcc/
            * config/riscv/riscv.md (length): Remove the explicit setting
            for "fcmp".
