[PATCH 1/4] target/ppc: Fix xs{max,min}[cj]dp to use VSX registers

[Victor Colombo]

PPC instruction xsmaxcdp, xsmincdp, xsmaxjdp, and xsminjdp are using
vector registers when they should be using VSX ones. This happens
because the instructions are using GEN_VSX_HELPER_R3, which adds 32
to the register numbers, effectively making them vector registers.

This patch fixes it by changing these instructions to use
GEN_VSX_HELPER_X3.
