* doc/tm.texi (HARD_REGNO_NREGS_HAS_PADDING,
HARD_REGNO_NREGS_WITH_PADDING): Document new target macros.
* defaults.h (HARD_REGNO_NREGS_HAS_PADDING,
HARD_REGNO_NREGS_WITH_PADDING): Define.

where the modes use different numbers of bits from registers.
* config/rs6000/rs6000.c (rs6000_emit_move): Handle TFmode
constant for soft-float.
(rs6000_hard_regno_nregs): Use UNITS_PER_FP_WORD for e500 GPRs
containing doubles.
(rs6000_split_multireg_move): Use DFmode reg_mode for TFmode moves
in E500 double case.
* config/rs6000/rs6000.md (movtf): Allow soft-float.
