[PATCH, i386]: Fix PR target/38931

Subject: [PATCH, i386]: Fix PR target/38931

Hello!

The problem was with the type of  *movsi_1 alternative 2 (and
*movdi_1_rex64 alternative 5) type. Gcc wants to analyze operand2,
which is nonexistent for "move-zero" instructions.

Attached patch changes type of these alternatives from mmxadd to mmx.

	PR target/38931
	* config/i386/i386.md (*movsi_1): Use type "mmx" for alternative 2.
	(*movdi_1_rex64): Use type "mmx" for alternative 5.

	* gcc.target/i386/pr38931.c: New test.
