Fix the check for CPU flags being used after an instruction that gets removed.
...
Previously only the next instruction was checked for usage of the CPU flags
but this fails for certain code.

Added/improved the optimizations:
...
* Added a new pass that optimizes PHA/PLA sequences
* Added a new pass that optimizes AND/EOR/ORA when an operand is known
* Added a run of an existing pass at later stages to remove code that
otherwise goes unchanged.
* Handle binary operations in OptUnusedLoads in addition to real loads.

The change from #2495 didn't take into account that recursive calls to main()
...
are legal in C. With the changes from #2495 , such calls will usually crash the
machine. But recursive calls to main() are rare and on the 6502 every byte
saved is precious. So this change limits the effect of #2495 to cc65 mode and
at the same time disallows recursive calls to main() in this mode. If
recursive calls to main() are actually required, the code must be compiled in
c89 or c99 mode.

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.
