This will tell loop idiom recognize that it can make popcount loops countable using the ctpop intrinsic. I didn't bother checking for illegal types. Type legalization knows how to split a ctpop into multiple ctops added together. Assuming we only receive reasonable integer bit widths, a few cpop instructions added together is probably better than the loop.
