Opened draft PR: https://github.com/vim/vim/pull/12192
Initial results are promising, one measure is how few loops are
required for the results to stabilize.
And the results show *faster times* when user defined functions
are involved. It's interesting how good that feels, even though
it doesn't mean anything is actually running faster in production.

You might want to store the hash number with the function to avoid the
overhead of computing it.
This still needs to be done. To make sure I understand,
this is saving `hash_hash(name)` in ufunc_T and has_profiling has an
additional argument which is the hash. And if this argument is zero
then the hash would be computed in has_profiling.
The overhead of looking up the key in the
table can't be avoided. Also, when more function names are being cached
updating the hash table can also take a noticable amount of time.
Yes, but it also would usually indicate that the table has been very useful.
I don't know most use cases; does the number of things being profiled
change dynamically or very often?
