[Compiler] Fix flaky tsan error for bytecode flushing. The SFI's flags can be changed by the mutator while the concurrent marker is checking the flags for bytecode flushing. None of the flag bits checked for bytecode flushing are changed, however since they are in an int32 field TSAN will complain if any of the other flags are changed while reading from another flag. Fix this by making the flags use the RELAXED_INT32_ACCESSORS.
