PowerPC TCG flushes the TLB on every IR/DR change, which basically

This brings the number of TLB flushes down from ~900000 to ~50000
for starting up the Debian installer, which is in line with x86
and gives a ~10% performance improvement.

So this patch seems to break my Debian squeeze image with -M g3beige.

$ ./ppc64-softmmu/qemu-system-ppc64 -vnc :3 -snapshot -M g3beige debian_squeeze_powerpc_standard.qcow2 -serial mon:stdio

I'll remove it from my queue for now.
