m68k: a bunch of '000 related fixes and cleanups. generated source now compiles for '000 again, which was broken due to recent improvements conflicting with limitations of the original '000

m68k: implemented second_addordinal; for the most trivial cases. this allows the right node to be a reference. falls back to the generic implementation for nontrivial cases.

m68k: support and use float TResFlags in the rest of the CG. ColdFire FPU now works, and FSxx is no longer generated which is software supported on '060, and doesn't exist on CF. if we still want to support it later, we can add it to cg.g_flags2reg

m68k: added cpu type cfv4e, which is the only ColdFire with FPU, and GNU AS needs this to actually allow CF FPU code

m68k: rewrote fixref and a_load_ref_ref, fixing a bunch of problems on ColdFire, unifying and simplifying the code a lot, and hopefully not killing anything in the process

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: 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.

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)
