86317711e0 IIgs SCC: Rework branches to X-indexed variables

8b71fafb84 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.

1fab179cb4 a BIT of 65C02 optimisations
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.

factorized, -128 bytes in programs using both fgets and gets.
