machmode.def (PARTIAL_INT_MODE): Add precision and name.
* machmode.def (PARTIAL_INT_MODE): Add precision and name.
* genmodes.c (PARTIAL_INT_MODE): Add precision and name.
(make_vector_mode): Increase namebuf to 16.
(emit_insn_modes_h): When processing BImode, don't
also match partial int modes.
(emit_class_narrowest_mode): Likewise.
* config/bfin/bfin-modes.def: Add precision to PDI.
