* config/rs6000/rs6000.h (HARD_REGNO_CALLER_SAVE_MODE): Use DFmode
to save TFmode registers and DImode to save TImode registers for
caller save operations.
(HARD_REGNO_CALL_PART_CLOBBERED): TFmode and TDmode do not need to
mark being partially clobbered since they only use the first
double word.
* config/rs6000/rs6000.c (rs6000_init_hard_regno_mode_ok): TFmode
and TDmode only use the upper 64-bits of each VSX register.
