c4x.c (c4x_emit_move_sequence): Force invalid QImode constants into memory if... 

* config/c4x/c4x.c (c4x_emit_move_sequence): Force invalid QImode
	constants into memory if we get called directly from gen_move_insn
	rather than emit_move_insn.
	(c4x_legitimize_address): Fix up LABEL_REF addresses.
