IIgs SCC: Allow choosing 115200bps as the card allows it
...
Of course, that won't work full speed with the standard
IRQ-based RX. But that will allow users to setup the port
at this speed without duplicating the setup part of the
code. Up to them to add hooks to disable IRQs and read
directly in a tight asm loop.

[SIM65] Support undocumented opcodes for 6502
...
This PR is mostly a complete rewrite of the emulator for 6502/65c02 opcodes.
It provides an easier to maintain implementation of the instructions, by using few macros rather than having hand-written code for each function.
All undocumented, previously missing opcodes for 6502 are also implemented.
The patch also includes a detailed documentation of those opcodes, for reference to developers.
This PR should fix one of the milestones listed here for the next version of CC65:

Use BIT immediate instead of AND when reloading A is required
afterwards.
Add an fread unit test as the optimisation touches fread.
Sprinkle a few zero page indexed while we're at it.
