  [PowerPC] Add handling for WACC register spilling.

This patch adds spilling for the new WACC registers.

In order to get the spilling test to work the MMA instructions from Power 10 are
now supported for Future CPU except that they are all using the new WACC
registers instead of the ACC registers from Power 10.
