Update x2y2m1 to use Ogita's dot-product summation in 3-fold precision. This has been tested with 1,000,000,000 random cis numbers with no ULP errors. The previous summation using Dekker's 2-fold precision sum had observed ULPs > 65000. Hard examples of cis-numbers have been added to the Complex edge-case test.
