Fix: Reduce constant-fold time for ARM from 20min+ to 10s

With the new interpreter changes computing the initial state for the
interpreter does some significant work. The existing code was
re-computing the initial state for every subexpression in the
specification (not even just the ones due to be constant-folded away).
Now we just compute the initial state once and use it for all constant
folds.

Also reduce the time taken for the simple_assignments rewrite from 20s
to under 1s for ARMv8.5, by skipping l-expressions that are already in
the simplest form.
