Log message:
	opcodes: blackfin: fix decoding of many invalid insns
	
	The Blackfin disassembler was originally based on the premise of parsing
	valid opcodes all the time, so some of the opcode checking can be a bit
	fuzzy.  This is exemplified in decoding of parallel insns where many
	times things are decoded as invalid when in reality, they may not be
	used in parallel combinations.  So add parallel checking to most insn
	decoding routines so we see ILLEGAL and not just whatever insn happens
	to be close to a valid mnemonic, as well as some additional sub-opcode
	checks.
