patch 8.1.1055: CTRL-G U in Insert mode doesn't work for shift-Left

Browse Source 
Problem:    CTRL-G U in Insert mode doesn't work to avoid splitting the undo
            sequence for shift-left and shift-right.
Solution:   Also check dont_sync_undo for shifted cursor keys. (Christian
            Brabandt)
