Subject: [PATCH, i386]: Fix PR target/43067, ICE: SIGSEGV with -fschedule-insns -mxop

Hello!

The problem was, that a couple of insns without third operand were marked as ssemuladd. Insns, marked as ssemuladd are checked on third operand to determine if insn loads or stores from memory. Mark these instructions as ssemul type, as this is what they do before splitting.
