5237a4d5e2 m68k: support register pair operands in assembler reader and writer, as used by some instructions (mainly DIVS/DIVU and friends) so we don't have to hack them as three operand instructions

258b42de26 m68k: added support for FSIN/FCOS. these are software supported on the 68040, so we should have a separate 68040/060 FPU option too, to avoid these in the future.

c062e55aa2 m68k: after a compare on the FPU, move the condition flags back to the CPU. this should make floating point compare actually working

d000b1bc7c m68k: basic 68881 fpu support. probably still broken at umpzillion places, and mostly untested, but at least it builds the RTL and all packages successfully with -Cp68020 -Cf68881 instead of dying with random internalerrors() and now even emits actual FPU opcodes.

b91d965096 * m68k: initial support for ROL/ROR operations, defining 'cpurox' for CPU target can actually enable them. However it cannot be done outright because these instructions do not exits on Coldfire, and internal processing of RoX,Sar,BsX, etc. can not yet be switched depending on CPU subtype.

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
