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.)
