Remove duplicate Javascript tree. This dupe was probably an artifact of the migration.

-/* __ieee754_atan2(y,x)
- * Method :
- *	1. Reduce y to positive by atan2(y,x)=-atan2(-y,x).
- *	2. Reduce x to positive by (if x and y are unexceptional): 
- *		ARG (x+iy) = arctan(y/x)   	   ... if x > 0,
- *		ARG (x+iy) = pi - arctan[y/(-x)]   ... if x < 0,
- *
- * Special cases:
- *
- *	ATAN2((anything), NaN ) is NaN;
- *	ATAN2(NAN , (anything) ) is NaN;
- *	ATAN2(+-0, +(anything but NaN)) is +-0  ;
- *	ATAN2(+-0, -(anything but NaN)) is +-pi ;
- *	ATAN2(+-(anything but 0 and NaN), 0) is +-pi/2;
- *	ATAN2(+-(anything but INF and NaN), +INF) is +-0 ;
- *	ATAN2(+-(anything but INF and NaN), -INF) is +-pi;
- *	ATAN2(+-INF,+INF ) is +-pi/4 ;
- *	ATAN2(+-INF,-INF ) is +-3pi/4;
- *	ATAN2(+-INF, (anything but,0,NaN, and INF)) is +-pi/2;
- *
- * Constants:
- * The hexadecimal values are the intended ones for the following 
- * constants. The decimal values may be used, provided that the 
- * compiler will convert from decimal to binary accurately enough 
- * to produce the hexadecimal values shown.
