02495c17bd Fix a typo. The CPU specific version of "ttypesym" should be called "tcputypesym" and not "tcpuypesym".

9c7c64a3af * moved amiga/morphos-specific libsym-related field from tprocdef to 
cpu-specific descendants (unfortunately causes some duplication, but the
    code is trivial and there is no easy way to avoid it)
  * also moved the use of the field in ncal to cpu-specific files (with same
    caveat)

classes

b57c95043f + support overriding tdef/tsym methods with target-specific functionality: 
o made all (non-abstract) tdef and tsym constructors virtual
   o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
     class
   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type
   o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
     calls

9ae38cdc1c back to more conservative sign extension. this really needs separate handling for ColdFire and normal 68k, because the CF executes 32bit arithmetics only while normal 68k will do any size happily.

a82a3ec38e 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)
