	PR target/57150
	* 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.
