 Reapply [AMDGPU] prevent shrinking udiv/urem if either operand exceeds signed max (#119325)

This reverts commit 254d206ee2a337cb38ba347c896f7c6a14c7f218.

+Added a fix in ExpandDivRem24 to disqualify if DivNumBits exceed 24.

Original commit & msg:
ce6e955ac374f2b86cbbb73b2f32174dffd85f25.
Handle signed and unsigned path differently in getDivNumBits. Using
computeKnownBits, this rejects shrinking unsigned div/rem if operands
exceed signed max since we know NumSignBits will be always 0.
