m68k: instead of trying to mess with LOC_FLAGS, use LOC_REGISTER to return a boolean result of the compare. idea by Florian. fixes several issues with optimizer enabled and also results in better code in some cases.

m68k: actually,overwrite the resflags with F_E, because only that would be valid after the FSxx/TST combination

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 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: further improved code generation for comparison nodes, support LOC_REFERENCE for 32-bit compares and omit low dword, when possible, for 64-bit ones.

* m68k: completely replaced 64-bit comparison code with a clone of i386 implementation. No optimizations yet, but it already makes system unit about 300 instructions shorter due to changing node location to LOC_JUMP.

* m68k: fixed comparison of small sets, it should not modify sides. tw18013 is now correct when compiled with -O2.

- m68k: dropped t68kaddnode.second_cmpboolean, apparently its presence just breaks tbs/tb0246 without any value added.

- m68k: removed some definitely misplaced code, comparison nodes are never handled in second_addfloat.

let the assembler decide about the size of the Bcc and BRA instructions, this makes code generated here work on a 68000 (and probably a lot smaller in size, no more forced 32bit displacements)
