[PATCH] Port for CRX architecture

["Paul Woegerer" <Paul dot Woegerer at nsc dot com>]

Hello,

i recently received my assignment to GCC project from the FSF.

Now i want to contribute my port for the CRX architecture. Later on
me or a colleague will contribute the binutils and we will also make
a CRX simulator available for free. But for now i would like to
contribute this initial GCC port.

So far there is still some work to do on optimizations and i do not
use any scheduling mechanism. Getting rid of cc0 is planned for near
future. As i am now working full time on this port its quality will
successively improve and fit more and more to the current GCC
standards.

The CRX is the next generation CompactRISC architecture
(http://www.compactrisc.com). This 32-bit architecture extends the
earlier CR16 family. It is optimized for minimal die size and a high
performance/power_consumption ratio.

Here is the Changelog entry for the GCC subdirectory:
