Analysis not updated after patching bytes in the hex view or linear view

[xusheng6]

1. Open helloworld.zip
2. Go to 0x11f0
3. Switch to hex view
4. Patch the bytes at 0x11f0 to 0xc3
5. Switch back to linear view
6. Notice the disassmelby of the instruciton is updated to ret, but the CFG of the function is not yet updated
   
7. Manually re-analyze the function, and notice the CFG is correctly updated:
   

My suspect is we are not triggering a full analysis on the function (which will re-calculate the CFG)

I looked into this and realized that we are indeed properly marking the function as update required when the memory bytes change, but the analysis is never updated. I checked current_function.needs_update returns True after the patch

This also affects the linear view -- e.g., the analysis is NOT updated after pasting a few bytes

Note this does not affect instruction patching (e.g., by using the E and then edit the instruction text) -- apparently that code path updates the analysis properly
