    * config/rs6000/rs6000.md (rreg): Add TFmode, TDmode constraints.
    (mov<mode>_internal, TFmode/TDmode): Split TFmode/TDmode moves
    into 64-bit and 32-bit moves.  On 64-bit moves, add support for
    using direct move instructions on ISA 2.07.  Also adjust
    instruction length for 64-bit.
    (mov<mode>_64bit, TFmode/TDmode): Likewise.
    (mov<mode>_32bit, TFmode/TDmode): Likewise.
