Remove a local variable from pop_1st_bit() Remove the 'b' uint32_t local variable. Optimized assembly is more or less the same (one 'mov' instruction less), but now it is written in a way more similar to the final assembly flow so it should be easier for compiler to optimize. Also guarantee that BitTable[] is always aligned. No functional change. Signed-off-by: Marco Costalba <mcostalba@gmail.com>
