Add VSR to Global Registers
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.
