ppc: Alter CPU state to mask out TCG unimplemented instructions as appropriate
The CPU state contains two bitmaps, initialized from the CPU spec which describes which instructions are implemented on the CPU. A couple of bits are defined which cover instructions (VSX and DFP) which are not currently implemented in TCG. So far, these are only used to handle the case of -cpu host because a KVM guest can use the instructions when the host CPU supports them. However, it's a mild layering violation to simply not include those bits in the CPU descriptions for those CPUs that do support them, just because we can't handle them in TCG. This patch corrects the situation, so that the instruction bits _are_ shown correctly in the cpu spec table, but are masked out from the cpu state in the non-KVM case.
