rs6000.c (legitimate_offset_address_p): Do not restrict DFmode and TFmode to word alignment.

* config/rs6000/rs6000.c (legitimate_offset_address_p): Do not
restrict DFmode and TFmode to word alignment.
* config/rs6000/rs6000.md (movdf_hardfloat64): Use 'o' constraint
for ld/std and order before mr.
