b2aceaea24 Fix behavior of .INCLUDE within a macro or .REPEAT. In the original code 
.INCLUDE was executed after expansion of the macro or .REPEAT - which was
wrong and caused all sorts of unexpected behavior. Related issues/PRs
are #231, #1473, #2159 and maybe others.

Note: After this change error messages for nested macro/.include statements
may be wrong. This is an unrelated bug that was always there and got exposed
by this fix. The bug needs to be addressed in a separate PR.

b5cc68d6e2 Do not save any register variables when entering main(). Do not restore the C 
stack when leaving main(). Both are unnecessary and just bloat the executable.

b04d79b1da [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:
