Fix the generation of alignment instructions for m68k. This not only fixes quite some tests, but most importantly the native m68k compiler!

* aggas.pas, TGNUAssembler.WriteTree.doalign:
    instead of strangely checking for the previous instruction always use .balignw if the previous code was code and we should not use a specific instruction
