ccecf2c13c Fix comparisons (aka usage of flag/CCR register) 
m68k/aasmcpu.pas, taicpu.spilling_get_operation_type:
  * add all Sxx instructions as "operand_write" instructions

m68k/n68kadd.pas, t68kaddnode.getresflags:
  * use the correct operation in case of swapped nodes

m68k/cgcpu.pas, tcg68k.g_flags2reg:
  - don't move a 0 to the register, because this will CLR it and thus the flags won't be valid anymore...
  - NEG would have been the wrong operation (NOT would have been correct), but it isn't needed anyway...
  * simplify the method by handling the address register case only when necessary

a23fa2e81e * moved (unfinished) routines related to writing taicpu's to ppu files 
from x86/aasmcpu to aasmtai and (new) aasmsym, so that when they're
    finished they're available for all targets
  * added dummy implementation of tai_cpu_abstract.pass1 and pass2 so there
    are no more hundreds of warnings on non-x86 about constructing taicpu
    instances with abstract methods
