[AMDGPU][GISel] Remove redundant AND on scalar shift amounts A scalar shift only consumes the low log2(bitwidth) bits of its amount, so an explicit (and amt, mask) feeding the amount is redundant whenever mask has all of those low bits set. SelectionDAG already achieves this via SimplifyDemandedBits on the shift-amount operand; this adds the equivalent to the post-RegBankSelect combiner for G_SHL/G_LSHR/G_ASHR.
