BALATON Zoltan 27a3ea7eff target/ppc: Fix msync to do what hardware does 
According to BookE docs, invalid bits (while undefined behaviour) should
not raise exception but be ignored. This seems to be implementation
dependent though and QEMU currently does what e500 CPUs do and raise
exception for invalid bits. Unfortunately some versions of libstdc++
(and so all programs compiled with it) have lwsync on PPC440 which is
invalid but on real hardware it's just executed as msync ignoring the
invalid bits (maybe that's why it got undetected) but they fail on QEMU.
This patch changes invalid mask of msync to allow these programs to run
but keep generating exception on e500 cores to follow what hardware does.
