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

m68k: BSET and BCLR's dest operand is actually readwrite, not write only. fixes sets with regvars, when the regvar is spilled

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: 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.
