e0cbd48785 m68k: always check the V flag after MUL/DIV overflows, because MUL/DIV never sets the C flag. note that this fix is full 68k only. on CF, MUL doesn't set any of V or C flags

4d41decd5d * since m68k has a working implementation for the register calling convention and it's in fact used as default calling convention it should also be possible to explicitely declare routines as that calling convention

a25ebbba3e + added volatility information to all memory references 
o separate information for reading and writing, because e.g. in a
     try-block, only the writes to local variables and parameters are
     volatile (they have to be committed immediately in case the next
     instruction causes an exception)
   o for now, only references to absolute memory addresses are marked
     as volatile
   o the volatily information is (should be) properly maintained throughout
     all code generators for all archictures with this patch
   o no optimizers or other compiler infrastructure uses the volatility
     information yet
   o this functionality is not (yet) exposed at the language level, it
     is only for internal code generator use right now
