19a6964088 m68k: add subregisters. on 68k, these are not as universal as on x86 and work differently, but the compiler needs this infrastructure to do 16bit math (which is a massive improvement on '000) or word-size indexes on CPUs which support it

d115b0e8dc m68k: changed the internal name of 68k MacOS from system_m68k_mac to system_m68k_macos, so it's consistent with the PowerPC version. suggestion/request by Sven :)

4e51dc2298 m68k: enable named sections for vasm generated objects. have a separate as_m68k_as_aout for a.out objects which doesn't have named sections. amiga and atari gas defaults to a.out, so have it default on these systems. finally enable section smartlinking for amiga and atari, which will be used with vasm assembler

991e1f49bd * store a pointer to the used tasminfo record in every assembler writer, so 
that we can use assembler writers with different conventions from the
    currently set target_asm (e.g. an x86 assembler writer for inline assembly
    in LLVM IR)

b3d0197f98 * factored out the output file handling (mostly writing data) from the 
external assembler writer, so we can reuse the archtecture-specific
    writers to write inline assembly in LLVM IR files

0217efc398 m68k/ag68kgas.pas, getreferencestring: 
It seems that GNU as needs the syntax "offset(register.size*scale)" if the base address
  register is ommited instead of "offset(,register.size*scale)". Now the System unit
  assembles and nearly the complete RTL can be built.

ac43eb9b70 + generic implementation of ReplaceForbiddenAsmSymbolChars() instead 
of the AVR-specific ifdef'ed variant
   o since the only special character we use in mangled names on all platforms
     is $, added a new field to tasminfo called "dollarsign" that holds the
     character $'s should be replaced with (if it doesn't have to be replaced,
     leave it at $)
