target/ppc: Optimise VSX_LOAD_SCALAR_DS and VSX_VECTOR_LOAD_STORE
A few small optimisations:
In VSX_LOAD_SCALAR_DS() we can don't need to read the VSR via
get_cpu_vsrh().
Split VSX_VECTOR_LOAD_STORE() into two functions. Loads only need to
write the VSRs (set_cpu_vsr*()) and stores only need to read the VSRs
(get_cpu_vsr*())
Thanks to Mark Cave-Ayland for the suggestions.
