[FRONTEND] Reduce number of compiles in JITFunction (#704)

Browse Source 
I suspect this was the cause of the "new compiles even on a warm cache"
behavior I was seeing, though haven't 100% confirmed it.

Python `set()` iteration order is nondeterministic when you create a new
process. So the same args could produce different `instance_descriptor`s
and have false cache misses.
