Correct cycle counts for W relative indexing modes
Actually handle the 6309 specific W relative indexing modes (,W; n,W; ,W++;
,--W) in the cycle count calculation code. These work differently than the
regular indexing modes so it's necessary to handle their bit patterns
specially. (The bits that would normally select the base register are used
instead to select the operation on W.)
