... and bms_prev_member(). Both of these functions won't work correctly when given a prevbit of INT_MAX and would crash when operating on a Bitmapset that happened to have a member with that value. Here we fix that by using an unsigned int to calculate which member to look for next. I've also adjusted bms_prev_member() to check for < 0 rather than == -1 for starting the loop. This was done as it's safer and comes at zero extra cost. With our current use cases, it's likely impossible to have a Bitmapset with an INT_MAX member, so no backpatch here. I only noticed this issue when working on a bms function to bitshift a Bitmapset.
