vim-patch:8.1.1684: profiling functionality is spread out

Browse Source 
Problem:    Profiling functionality is spread out.
Solution:   Put profiling functionality in profiling.c. (Yegappan Lakshmanan,
            closes vim/vim#4666)
fa55cfc69d

Move proftime_T to types.h for now to avoid recursive #include.
