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.

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

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

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.

* 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.

* 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
