0f6ab0de17 * handle LOC_(C)SUBSETREG/REF in second_NegNot_assign 
* changed the way OP_NEG and OP_NOT are handled in op_reg_ref, in order to be
  consistent with op_reg_reg
* introduced op_reg,op_ref,op_subsetreg,op_subsetref and op_loc for the unary
  operations only (OP_NEG,OP_NOT)

4686f61002 * keep track of the temp position separately from the offset in references,

tcpuparamanager, very similar to the existing get_volatile_registers_XXX. The
  new methods are called get_saved_registers_XXX, where XXX is the register
  type ("int", "address", "fpu" or "mm")

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
