27e1c5c9f8 Make Register16 a class, rather than struct. Tricky, but a bit faster than before.

3108a373d7 Interesting: in profiling, creating the mapping object was one of the major bottlenecks, when running the M6502 test suite.

63db46a7bc Resurrect the Register16 class. This (or something *very* much like it) is going to be necessary to add a Z80 emulator (reference access to the high/low parts of 16-bit registers).

d4a35c402c A few small consistency updates: 
1) Drop Get/SetPagedByte in favour of normal BusRead/Write
2) Tidy some "using" statements
3) More "expression body" usage, if possible
4) Use field initialisation, rather than construction, if possible
5) Correct IntelProcessor register set/get methods (there were remnants of "copy pasta" code)
