    Fix incorrect insn type to avoid ICE in memory attr auto-detection.
    
    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.
    
    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.
