ReleaseNotes: Move SystemZ so it doesn't come between the static analyzer 

and clang-tidy sections, which concern similar functionality.

* Various improvements to the retain count checker.





SystemZ

-------



* Clang will now always default to the z10 processor when compiling

  without any ``-march=`` option. Previous releases used to automatically

  detect the current host CPU when compiling natively. If you wish to

  still have clang detect the current host CPU, you now need to use the

  ``-march=native`` option.



* Clang now provides the ``<s390intrin.h>`` header file.



* Clang now supports the transactional-execution facility and

  provides associated builtins and the ``<htmintrin.h>`` and

  ``<htmxlintrin.h>`` header files. Support is enabled by default

  on zEC12 and above, and can additionally be enabled or disabled

  via the ``-mhtm`` / ``-mno-htm`` command line options.



* Clang now supports the vector facility. This includes a

  change in the ABI to pass arguments and return values of

  vector types in vector registers, as well as a change in

  the default alignment of vector types. Support is enabled

  by default on z13 and above, and can additionally be enabled

  or disabled via the ``-mvx`` / ``-mno-vx`` command line options.



* Clang now supports the System z vector language extension,

  providing a "vector" keyword to define vector types, and a

  set of builtins defined in the ``<vecintrin.h>`` header file.

  This can be enabled via the ``-fzvector`` command line option.

  For compatibility with GCC, Clang also supports the

  ``-mzvector`` option as an alias.

 

* Several cases of ABI incompatibility with GCC have been fixed.
