#1298: Data.Complex.phase does unnecessary pattern match

----------------------+-----------------------------------------------------
The Data.Complex.phase function contains this line:
phase (0 :+ 0) = 0 -- SLPJ July 97 from John Peterson
This is not necessary since atan2 (invoked on the following line) is
defined such that it returns 0 in this case already.
