How to count the number of set bits in a 32-bit integer?

...all enough counts) that this doesn't produce carry into that top 8 bits. A 64-bit version of this can do 8x 8-bit elements in a 64-bit integer with a 0x0101010101010101 multiplier, and extract the high byte with >>56. So it doesn't take any extra steps, just wider constants. This is what GCC...
