536959619f Refine the horizontal dispatch 
Find small optimizations to improve the average performance of the
blitter, especially in the odd-aligned case.

 - Odd-aligned PEA exit is 2 cycles faster per line
 - Odd-aligned JMP exit is 2 cycles faster per line
 - Odd-aligned LDA exit is 6 cycles faster (eliminated long store)
 - Merged setting the entry opcode and offset to convert 2 8-bit
   store into a single 16-bit store (save 6 cycles per line)
 - Load and save the full word for the high bytes. Cost 2 cycles
   but enabled the 6 cycles saved for the LDA case.
