m68k: use a_load_ref_ref in a_load_ref_cgpara instead of a custom loading code which does the same. causes no changes in generated code

m68k: only extend the dest reg to tosize during reg-reg moves. this removes a large amount of unnecessary sign and zero extensions from the generated code. this was attempted before, but thanks to other fixes it no longer causes testsuite regressions

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: use a_load_const_ref in a_load_const_cgpara to utilize the recently added optimized small const loading here too. this change alone shaves off ~80KB from the compiled FP IDE size...

m68k: if we're loading small (8 bit signed) values into long references, move them through a register (usually with MOVEQ). this is two bytes shorter and also faster on most 68k CPUs

m68k: disabled premature MOVEA #0,Ax to SUBA Ax,Ax in the CG, because it breaks with spilling temp replacement and moved it to the optimizer, where it belongs. this fixes some code with potentially heavy address register pressure, like the IDE.

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.
