m68k: when loading from a reference with zero extend, clear the register first, then load, instead of clearing with AND later, because this is faster on slow 68ks and also shorter

m68k: add a function to optimize const MUL cases to sequences of shifts + ADD/SUB. mainly for '000 and other low end 68ks with slow/limited MUL capabilities. inactive for now, as it wasn't that extensively tested

m68k: removed obsolete and wrong comment. the '881 extended type is actually 12 bytes during load/store, not 10, which means longword alignment is fine. no functional changes.

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
