Add POWER7 support for ppc

Browse source 
This adds emulation support for the recent POWER7 cpu to qemu.  It's far
from perfect - it's missing a number of POWER7 features so far, including
any support for VSX or decimal floating point instructions.  However, it's
close enough to boot a kernel with the POWER7 PVR.
