For PR1248: * Fix some indentation and comments in InsertRangeTest * Add an "IsSigned" parameter to AddWithOverflow and make it handle signed additions. Also, APIntify this function so it works with any bitwidth. * For the icmp pred ([us]div %X, C1), C2 transforms, exit early if the div instruction's RHS is zero. * Finally, for icmp pred (sdiv %X, C1), -C2, fix an off-by-one error. The HiBound needs to be incremented in order to get the range test correct. llvm-svn: 35247
