85f814c632 Attempt to build fixed operations into type. 
This simplifies callees and should make all helper functions automatically able to optimise themselves for fixed operations.

bf5ed98f35 Generalise 65c02 behaviour. 
Partly to convince myself:
1. this change alters behaviour of `CycleAddXToAddressLowRead`
2. which affects only `AbsoluteXw` and the 65c02-specific `JMP (abs, x)`;
3. `AbsoluteXw` is then used only by `AbsoluteXWrite` and `AbsoluteXReadModifyWrite`;
4. `AbsoluteXWrite` is used for abs, x addressing by `SHY`, `STA` and `STZ`;
5. `AbsoluteXReadModifyWrite` is used for `ASL`, `ASO`, `ROL`, `RLA`, `LSR`, `LSE`, `ROR`, `RRA`, `DEC`, `DCP`, `INC` and `INS`.

... though many of the latter are replaced by instance of `FastAbsoluteXReadModifyWrite` for the 65c02 which don't include a dummy
access at all if the page boundary is crossed so the issue is moot.

5c7f94d2ef Introduce the possibility of operation type as a template parameter. 
It's already proven possible to provide this for instruction fetch, so I think it'll immediately be a win. But more importantly it opens a path forwards for further improvement.
