	* tic80-opc.c (V_a, V_m, V_S, V_Z, V_p, OP_V, MASK_V):
	New macros for building vector instruction opcodes.
	(tic80_opcodes): Remove all uses of FMT_SI, FMT_REG, and
	FMT_LI, which were unused.  The field is now a flags field.
	Remove some opcodes that are possible, but illegal, such
	as long immediate instructions with doubles for immediate
	values.  Add "vadd" and "vld" instructions.
