builtins.c (cos_builtin, [...]): Delete.

Browse Source 
* builtins.c (cos_builtin, sin_builtin, sqrt_builtin): Delete.
	(builtin_record): Add an additional builtin_code field to
	record which GCC built-in corresponds to the Java function.
	(java_builtins):  Add new entries for atan, atan2, exp, log,
	pow and tan.
	(max_builtin, min_builtin, abs_builtin): Perform constant
	folding on the resulting tree.
	(java_build_function_call_expr): Likewise, perform constant
	folding on the resulting tree.
	(initialize_builtins): The NULL creators are now allowed in
	the java_builtins table, which is now terminated by an entry
	with builtin_code == END_BUILTINS.
	(check_for_builtin): Likewise.  If the matching creator is
	NULL, construct the call using java_build_function_call_expr
	directly with the decl for the corresponding builtin_code.
