* tic80.h (struct tic80_opcode): Change "format" field to "flags". 

(FMT_UNUSED, FMT_SI, FMT_LI, FMT_REG): Delete.
	(TIC80_VECTOR): Define a flag bit for the flags.  This one means
	that the opcode can have two vector instructions in a single
	32 bit word and we have to encode/decode both.

base relative.
