    Micro optimization for Sparc. The ftruncate code using · 95f890d7

    %unary-truncate has many redundant stack moves even when it's know the
    result will fit in a (signed-byte 32), so create vops to do the
    conversion directly in the floating-point registers.
    
    Also, sparc-v9 can do 64-bit integer conversions, so make the range up
    to 64-bits for sparc-v9.
