* builtins.c (fold_builtin_strcpy): Merge functionality from

	* builtins.c (fold_builtin_strcpy): Merge functionality from
	simplify_builtin_strcpy.  Add additional len argument.  No longer
	static.  Remove function prototype.
	(fold_builtin_strncpy): Likewise integrate functionality from
	simplify_builtin_strncpy.  Add additional slen argument.  No
	longer static.  Remove function prototype.
	(simplify_builtin_strcy, simplify_builtin_strncpy): Delete.
	(simplify_builtin_fputs): Rename to fold_builtin_fputs.  Change
	types of "ignore" and "unlocked" parameters to bool.
	(fold_builtin_1):  Add additional ignore argument.  Call renamed
	fold_builtin_fputs to simplify GCC "fputs" and "fputs_unlocked"
	builtins.  Update arguments to fold_builtin_strncpy and
	fold_builtin_strcpy.  Add function prototype.
	(fold_builtin): Add additional Boolean ignore argument to pass
	to fold_builtin_1.
	(simplify_builtin): Call fold_builtin_fputs, fold_builtin_strcpy
	and fold_builtin_strncpy instead of simplify_builtin_fputs,
	simplify_builtin_strcpy and simplify_builtin_strncpy respectively.

	* expr.h (simplify_builtin_fputs, simplify_builtin_strcpy,
	simplify_builtin_strncpy): Delete function prototypes.
	* tree.h (fold_builtin_fputs, fold_builtin_strcpy,
	fold_builtin_strncpy): Add function prototypes here.
	(fold_builtin): Update function prototype with new "bool ignore".

	* tree-ssa-ccp.c (ccp_fold): Update call to fold_builtin.
	(ccp_fold_builtin):  Update call to fold_builtin.  Call
	fold_builtin_fputs, fold_builtin_strcpy and fold_builtin_strncpy
	instead of simplify_builtin_fputs, simplify_builtin_strcpy and
	simplify_builtin_strncpy respectively.
	* fold-const.c (fold): Update call to fold_builtin.
