Memory write instructions should always use the maximum number of cycles whether they cross a page boundary or not. This affects: STA, DEC, INC, ROL, ROR, ASL, LSR. It looks like an attempt was made to handle the "6502 Jump Bug" but it wasn't done quite right. This change implements the bug correctly.
