* builtins.c (define_builtin_type, builtin_types): Delete.

	(define_builtin): Rewritten to take just the built-in code,
	the function's name, type and fallback library function name.
	All built-ins used by Java are implicit and BUILT_IN_NORMAL.
	(initialize_builtins): Overhaul to define the GCC builtins
	used by gcj manually, providing the Java run-time's
	implementations as the fallback library function.

	* libjava.lang/MathBuiltin.java: New test case.
	* libjava.lang/MathBuiltin.out: New file.
