* target.def (default_floatn_mode): Return an opt_scalar_float_mode.
* doc/tm.texi: Regenerate.
* config/arm/arm.c (arm_floatn_mode): Return an opt_scalar_float_mode.
* config/powerpcspe/powerpcspe.c (rs6000_floatn_mode): Likewise.
* config/rs6000/rs6000.c (rs6000_floatn_mode): Likewise.
* targhooks.h (default_floatn_mode): Likewise.
* targhooks.c (default_floatn_mode): Likewise.
* tree.c (build_common_tree_nodes): Update accordingly.
