Adding the following to config/rs6000/e500.h will likely fix the bug. 
Testing..

#define HARD_REGNO_CALLER_SAVE_MODE(REGNO, NREGS, MODE) \
  (TARGET_E500_DOUBLE && ((MODE) == DFmode || (MODE) == TFmode          \
                          || (MODE) == DCmode || (MODE) == TCmode)      \
   ? (MODE)                                                             \
   : choose_hard_reg_mode ((REGNO), (NREGS), false))
