[X86]Add NO_REVERSE attribute to X86 RMW instrs in memfold table (llvm#67288)

X86 don't want to unfold RMW instrs to 1 load + 1 op + 1 store, because
RMW could save code size and benefit RA when reg pressure is high.
And from all the call position analysis, we could find we didn't unfold
RMW in current code.
