42e0f8f9ce Unbreak Z3 C++ API exception support for GCC < 5.0. This was broken 
by 0b1d564509 .

Older versions of GCC do not define `__cpp_exceptions` which caused
exceptions to not be raised leading to unexpected failures. To fix
this also check the `__EXCEPTIONS` macro which is used by older GCC
versions.

Also `#undef` the `Z3_THROW` macro at the end of the header file
because this is an implementation detail that we don't want to leak
to clients.

[WIP][CMake] Fix broken regeneration of some .cpp files

d00892c9a6 [CMake] Fix dependencies for generating mem_initializer.cpp. 
Previously CMake was not aware of which headers files the generation
of `mem_initializer.cpp` depended on. Consequently this could result
in broken incremental builds if

* Existing headers that declare memory initializers/finalizers change.
* New headers are added that declare memory initializers/finalizer.

Now the `z3_add_component()` CMake function has been modifed so that
it now takes an optional `MEMORY_INIT_FINALIZER_HEADERS` argument
which allows the headers that declare memory initializers/finalizers
to be explicitly listed.

With this information CMake will now regenerate `mem_initializer.cpp`
correctly.

This required the `mk_mem_initializer_cpp_internal()` function to be
changed to take a list of header files rather than a list of component
source directories. The two consumers (CMake and Python/Makefile build
systems) of this function have been modified to work with this change.

This partially fixes #1030.

6f48a145aa [CMake] Fix dependencies for generating gparams_register_modules.cpp. 
Previously CMake was not aware of which headers files the generation
of `gparams_register_modules.cpp` depended on. Consequently this could result
in broken incremental builds if

* Existing headers that declared module description/parameters change.
* New headers are added that declare module description/parameters.
* `.pyg` files that generate header files that declare module
  description/parameters change

Now the `z3_add_component()` CMake function has been modifed so that

* All header files that are generated from `.pyg` files are added as
dependencies and are scanned from module description/parameter
declarations. This implicit dependency of `gparams_register_modules.cpp`
depending on other generated header files seems unnecessary complex. We
should revisit this design decision once the Python/Makefile build
system is deprecated.

* The function now takes an optional `EXTRA_REGISTER_MODULE_HEADERS`
argument which allows the headers that declare module
description/paramters to be explicitly listed.

With this information CMake will now regenerate `gparams_register_modules.cpp`
correctly.

This required the `mk_gparams_register_modules_internal()` function to be
changed to take a list of header files rather than a list of component
source directories. The two consumers (CMake and Python/Makefile build

* Existing headers that declared tactics/probes changed.
* New tactics/probes were added to new header files.

Now the `z3_add_component()` CMake function has been modifed to take an
optional `TACTIC_HEADERS` argument which allows the headers that declare
tactics/probes to be explicitly listed. The necessary component
declarations have been modified to declare their tactic/probe header
files.

With this information CMake will now regenerate `install_tactic.cpp`
correctly.

This required the `mk_install_tactic_cpp_internal()` function to be
changed to take a list of header files rather than a list of component
source directories. The two consumers (CMake and Python/Makefile build
