Marks < and > are overwritten too soon

[chtenb]

Describe the bug
The marks > and < are overwritten as soon as visual mode is entered.
This is not how vim behaves, and renders these marks useless in that scenario.
A related problem is that gv does not work from visual mode, while it should select the previously made visual selection.

To Reproduce
Steps to reproduce the behavior:

1. Enter Visual mode and select something.
2. Exit to normal mode and move somewhere else.
3. Enter visual mode.
4. Press < or > and notice this will not work as expected. Actuall `> will shift one place to the right, but that is because of this other bug: The `> register is off by one position. #3065
