Unify gcc.target/i386/memcpy scan strings.

After -fno-common became the default, we can unify various
scan strings between 64bit and 32bit targets.

	* gcc.target/i386/memcpy-strategy-1.c (dg-final):
	Unify scan-assembler strings for all targets.
	* gcc.target/i386/memcpy-strategy-2.c (dg-final): Ditto.
	* gcc.target/i386/memcpy-strategy-3.c (dg-final): Ditto.
	* gcc.target/i386/memcpy-vector_loop-1.c (dg-final): Ditto.
