code review 419042: Revert previous change: complexN only converts to complexN.

Revert previous change: complexN only converts to complexN.

This was discussed with Ken and Russ.  6g has been changed,
and both compilers now work this way.  This avoids a double
type conversion--first to the float type, then to the complex
type.

Hello r (cc: golang-dev@googlegroups.com, ken2, rsc),

I'd like you to review this change.

This was discussed with Ken and Russ.  6g has been changed,
