  1. Simplify HUF_decompress4X2_usingDTable_internal_bmi2_asm_loop 

    Get rid of three divisions. The original expression was:

    opmin := min((oend0 - op0) / 10, (oend1 - op1) / 10, (oend2 - op2) / 10, (oend3 - op3) / 10)
    r15   := min(r15, opmin)

The division by 10 can be moved outside the `min`:

    opmin := min(oend0 - op0, oend1 - op1, oend2 - op2, oend3 - op3)
    r15   := min(r15, opmin/10)
