opcodes i386 and ia64 gen file warnings

i386: warning: format ‘%u’ expects argument of type ‘unsigned int’,
but argument 4 has type ‘size_t’ {aka ‘long unsigned int’} [-Wformat=]
ia64: warning: ignoring return value of ‘fgets’

	* i386-gen.c (process_i386_opcodes): Correct format string.
	* ia64-gen.c (load_insn_classes, load_depfile): Don't ignore
	fgets return value.
