0353fc38ff fix #6127 again 
this time adding inheritance to the recfun plugin so it properly contains the recursive definitions from the source.

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.

73a24ca0a9 remove '#include <iostream>' from headers and from unneeded places 
It's harmful to have iostream everywhere as it injects functions in the compiled files

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.

81d97a81af enable nested ADT and sequences 
add API to define forward reference to recursively defined datatype.
The forward reference should be used only when passed to constructor declarations that are used in a datatype definition (Z3_mk_datatypes). The call to Z3_mk_datatypes ensures that the forward reference can be resolved with respect to constructors.
