* cpustate.c: Remove space after asterisk in function parameters.
	* decode.h (greg): Delete unused function.
	(vreg, shift, extension, scaling, writeback, condcode): Likewise.
	* simulator.c: Use INSTR macro in more places.
	(HALT_NYI): Use sim_io_eprintf in place of fprintf.
	Remove extraneous whitespace.
