Ziqiao Kong 0b30735d38 target/i386: Generate an illegal opcode exception on cmp instructions with lock prefix 
target/i386: As specified by Intel Manual Vol2 3-180, cmp instructions
are not allowed to have lock prefix and a `UD` should be raised. Without
this patch, s1->T0 will be uninitialized and used in the case OP_CMPL.
