Memory attribute auto detection will check operand 2 for type sselog,
and check operand 1 for type sselog1. For below 2 insns, there's no
operand 2. Change type to sselog1.

Bootstrapped and regtested on x86_64-pc-linux-gnu{-m32,}.
Ok for trunk?

gcc/ChangeLog:

	PR target/107540
	* config/i386/sse.md (avx512f_movddup512<mask_name>): Change
	type from sselog to sselog1.
	(avx_movddup256<mask_name>): Ditto.

gcc/testsuite/ChangeLog:

	* gcc.target/i386/pr107540.c: New test.

Committed as an obvious fix.
