6d7cf520 - [ValueTracking] Improve KnownBits for signed min-max clamping (#120576)

[ValueTracking] Improve KnownBits for signed min-max clamping (#120576) A signed min-max clamp is the sequence of smin and smax intrinsics, which constrain a signed value into the range: smin <= value <= smax. The patch improves the calculation of KnownBits for a value subjected to the signed clamping.
