builtins.c (expand_builtin_cabs): Delete.

2004-09-02  Eric Christopher  <echristo@redhat.com>

	* builtins.c (expand_builtin_cabs): Delete.
	(expand_builtin): If unable to fold the values do a normal
	library call for builtin_cab*.
	(fold_builtin_cabs): Depend on optimize and optimize_size.
	* optabs.c (expand_cmplxdiv_straight): Delete.
	(expand_cmplxdiv_wide): Ditto.
	(expand_vector_binop): Ditto.
	(expand_vector_unop): Ditto.
	(expand_complex_abs): Delete.
	(expand_binop): Remove calls to above functions.
	Remove open coding of complex arithmetic.
	(expand_unop): Ditto.
	* optabs.h: Remove prototypes.
