target-ppc: Define Endian-Correct Accessors for VSR Field Access
This change defines accessors for VSR doubleword and word fields that are correct from a host Endian perspective. This allows code to use the Power ISA indexing numbers in code. For example, the xscvdpsxws instruction has a target VSR that looks like this: 0 32 64 127 +-----------+--------+-----------+-----------+ | undefined | SW | undefined | undefined | +-----------+--------+-----------+-----------+ VSX helper code will use VsrW(1) to access this field.
