Subject: vim-patch:8.2.3944: insert mode completion functions are too long

Problem:    Insert mode completion functions are too long.
Solution:   Split up into multiple functions. (Yegappan Lakshmanan,
            closes vim/vim#9431)
https://github.com/vim/vim/commit/5d2e007ccbfbd749a1f201d06965b8811ff50e6e

Cherry-pick can_cindent_get() -> get_can_cindent() from patch 8.1.2062.
