This patch adds support for the Zawrs ISA extension.
The patch depends on the corresponding Binutils patch
to be usable (see [1])
The specification can be found here:

Note, that the Zawrs extension is not frozen or ratified yet.

The guard generation for a static var init was overly verbose. We can
use a bit of RAII and avoid some rechecking. Also in the !cxa_atexit
