1*9880d681SAndroid Build Coastguard Worker; Test several VSX FMA mutation opportunities. The first one isn't a 2*9880d681SAndroid Build Coastguard Worker; reasonable transformation because the killed product register is the 3*9880d681SAndroid Build Coastguard Worker; same as the FMA target register. The second one is legal.
