Fix slow compilation of huge functions
Some huge functions would compile very slowly because of a bottleneck
in `beam_ssa:def_used/2`. One example is the `cuter_binlib` module in
https://github.com/cuter-testing/cuter. On my computer, this commit
reduces the compilatation time for `cuter_binlib` to 45 seconds down
from more than 4 minutes.
