03385bf78d improve quantifier elimination for arithmetic 
This update changes the handling of mod and adds support for nested div terms.

Simple use cases that are handled using small results are given below.

```
(declare-const x Int)
(declare-const y Int)
(declare-const z Int)
(assert (exists ((x Int)) (and (<= y (* 10 x)) (<= (* 10 x) z))))
(apply qe2)
(reset)

(declare-const y Int)
(assert (exists ((x Int)) (and (> x 0) (= (div x 41) y))))
(apply qe2)
(reset)

(declare-const y Int)
(assert (exists ((x Int)) (= (mod x 41) y)))
(apply qe2)
(reset)
```

The main idea is to introduce definition rows for mod/div terms.
Elimination of variables under mod/div is defined by rewriting the variable to multiples of the mod/divisior and remainder.

The functionality is disabled in this push.

6835522a7f z3++.h: No longer include unused sstream. 
This makes some code using the C++ API have to include `<sstream>`
if they used the functionality but didn't include it themselves.

a9b7348b4b (cmake): fix visibility on shell z3 binary 
Commit #b361226 changed symbol visibility from a global to a local option.
This creates inconsistency for shell that is compiled as an executable rather
than as z3 component.

This commit adds same local options to shell target in cmake.

Prior to the fix, clang on OSX complains with lots of warnings about symbol visibility
being different in different translation units that are linked together

In older versions, this was dependent upon the version of cmake,
but when it was updated for newer cmake, these remnants were

9a99c78ffb Enable thread_local code more broadly. 
This was only being enabled on Windows, Linux, and FreeBSD. (FreeBSD
only had it enabled in the legacy build system, not in cmake.)

`thread_local` is part of C++11, so now that we require C++17
or later and more recent compilers, this should work everywhere
that threading does, so only disable it within a `SINGLE_THREAD`
build.

82d853e5f8 Use = delete to delete special methods. 
This provides a better experience than just marking them as
private and leaving them as undefined symbols.
