* gcc.c-torture/execute/memcpy-2.c (SEQUENCE_LENGTH): Define.
	(MAX_COPY): Bump up to 10 times sizeof (long long).
	(main): Use a pattern of SEQUENCE_LENGTH different characters to copy.

	* gcc.c-torture/execute/memset-1.c (MAX_COPY): Bump up to 10 times
	sizeof (long long).

	* gcc.c-torture/execute/strcpy-1.c: New test.
