[4.5] Power7 combined patches

[Michael Meissner <meissner at linux dot vnet dot ibm dot com>]

The enclosed file contains my current patches against the mainline to add
Power7 support to the rs6000 port.  With this patch, I have bootstrapped the
compiler on a Powerpc64 linux system (both a normal boostrap and a bootstrap
using BOOT_CFLAGS='-g -O2 -mcpu=power7').  With the compiler built, I get no
regressions compared to an unpatched tree.  There is still work to be done on
the Power7 port, but this is a reasonable stopping point.

Are there any comments people have about the patches?  I realize it is a big
patch, but that is the nature of the beast when adding a whole new instruction
set, particularly when the mainline is locked for new development.
