Subject: 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.
	* config/m32c/m32c-modes.def: Add precision to PSI.
	* config/msp430/msp430-modes.def: Add precision to PSI.
	* config/rs6000/rs6000-modes.def: Add precision to PTI.
	* config/sh/sh-modes.def: Add precision to PSI and PDI.
