ea2a843325 flat only 
remove option for uzers (users who are in reality fuzzers) to toggle flat option. The legacy arithmetic solver bakes in assumptions about flat format so it isn't helpful to expose this to fuzzers, I mean uzers.

Nikolaj Bjorner
202ce1edf0 #6100 - two perf fixes 
remaining perf bug is dealing with very large bit-widths. mod 2^n should be computed natively based on n instead of 2^n because we pre-populate an array with all values up to n. Suppose n is 10000, the array has size 10000.

477e9625ef Don't reset the cache between applications of replace 
tactic/lia2card shows a huge slowdown because the same replace function is called on thousands of assertions. Each time the cache gets reset with thousands of entries - they are all the same.
So don't reset the cache just because... Instead reset the cache if m_refs grows large.

fc77345bec breaking change. Enforce append semantics everywhere for parameter updates #5744 
Replace semantics doesn't work with assumptions made elsewhere in code.
The remedy is to apply append (override) semantics for parameter changes.
