[X86] Add mayLoad/mayStore to legacy instructions CMPS/LODS/MOVS/SCAS/STOS (llvm#185689)
When LLVM is used to disassemble instructions, legacy X86 strings instructions doesn't report memory access with mayLoad and mayStore. Note that INS and OUTS may also need sush flags, but I'm not totally sure which one.
