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.
