Simplify and specialize the even/odd patching
...
Allows the odd case to be slightly more efficient and the
code is cleaned up by not having to handle both even and odd
alignment cases at multiple points.

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.
