Changes
  1. [InstCombine] Fold select (icmp sgt x, -1), lshr (X, Y), ashr (X, Y) to ashr (X, Y))

    Summary:
    (select (icmp sgt x, -1), lshr (X, Y), ashr (X, Y)) -> ashr (X, Y))
    (select (icmp slt x, 1), ashr (X, Y), lshr (X, Y)) -> ashr (X, Y))

    Fixes PR41173

    Alive proof by @lebedev.ri (thanks)
    Name: PR41173
      %cmp = icmp slt i32 %x, 1
      %shr = lshr i32 %x, %y
      %shr1 = ashr i32 %x, %y
      %retval.0 = select i1 %cmp, i32 %shr1, i32 %shr
      =>
      %retval.0 = ashr i32 %x, %y

    Optimization: PR41173
    Done: 1
    Optimization is correct!
