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

Browse source 
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.
