[PATCH] lower-bitint: Fix up handling of unsigned INTEGER_CSTs operands with lots of 1s in the upper bits [PR113334]

Hi! For INTEGER_CST operands, the code decides if it should emit the whole INTEGER_CST into memory, or if there are enough upper bits either all 0s or all 1s to warrant an optimization, where we use memory for lower limbs or even just an INTEGER_CST for least significant limb and fill in the rest
