This patch adds VSX VSRs to the the list of global register indices.
More specifically, it adds the lower halves of the first 32 VSRs to
the list of global register indices. The upper halves of the first
32 VSRs are already defined via cpu_fpr[]. And the second 32 VSRs
are already defined via the cpu_avrh[] and cpu_avrl[] arrays.

IBM POWERPC processors encode PVR as a CPU family in higher 16 bits and
a CPU version in lower 16 bits. Since there is no significant change
in behavior between versions, there is no point to add every single CPU
version in QEMU's CPU list. Also, new CPU versions of already supported
CPU won't break the existing code.
This adds PVR value/mask support for KVM, i.e. for -cpu host option.
As CPU family class name for POWER7 is "POWER7-family", there is no need
to touch aliases.
