c49c8210a3 m68k: some initial HLCG, use BSET/BCLR instructions for simple bit manipulation

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.

997ec578e0 m68k: added a simple unaryminusnode which can utilize FNEG instruction for floats on 68881

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

a99c9c29b6 m68k: basic 68881 FPU register save/restore support. probably still needs some work here and there.

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.

d561e8ab57 m68k: generate smarter shifting/rotation code on 68k, for example by utilizing the SWAP instruction

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.

babbc21afd * fix handling of register sets on m68k: it is required that they are stored as two tcpuregistersets because address registers and data registers have different register types

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
