Dan Liew f27ac24fa0 Add example of using Z3's new model construction C API. This API 
was requested in #1223.

This example uses the new `Z3_mk_model()`, `Z3_add_const_interp()`
, `Z3_add_func_interp()`, and `Z3_mk_as_array()` API calls.

Dan Liew 7c99721b60 [TravisCI] Don't run Python regression tests under ASan for now. 
The script that runs them doesn't propagate LD_PRELOAD and so the
tests fail.

Dan Liew ead6e56d15 [TravisCI] Swap run_quiet and run_non_native_binding. In the
