I think avoid recording breakpoints is the main affect.
Another function is help deal with displaced step. Of course, P record
and displaced step will not work together now.
I think I add "record_not_record" function is because I want
record_store_registers and record_xfer_partial just record the user
level change, not for others.
What do you think about it?

I have no idea on it.
What about change the name to "record_skip_recording_gdb_behavior"?
