e93660c170 - removed ttai_lowleveltypedconstbuilder.queue_addrn(), as we are always 
implicitly taking the address of a complex expression in a typed constant
    (you cannot put the contents of another memory location in a typed
    constant)

9118146bc1 * ensure that managed out-parameters are processed before any other 
parameters:
   1) since they are finalised on the caller side, if that same value
      is passed as a value parameter as well and its reference count
      was 1, then the value parameter will contain an invalid pointer
   2) since finalisation involves a call, for optimal code generation
      purposes they should also be evaluated first
    (mantis #28279, #28390)

945fd4fcf5 * wait till the end of typecheckpass before we load a call context's self 
parameter instead of immediately doing it in the constructor of the call
  node, and then only create it if we actually need it.

  It was previously created in the call node constructor because it needs to be
  done before pass_1 (which is where it is actually used) due to pass_1 possibly
  being performed in the context of inlining (and then a wrong self parameter
  may be found, or none at all), and it was done unconditionally because at that
  point we don't know yet whether or not a self parameter will be necessary (as
  we haven't resolved the overloads/procdef yet).

  The problem with this is that if we use the parentfpstruct way of handling
  accesses to outer scope locals/parameters, we need to know all locals/
  parameters that will be accessed from nested routines after typecheckpass,
  otherwise we get crashes. The problem was that if a call to an RTL routine was
  generated by the compiler in a routine nested inside a method during pass_1,
  and this nested routine itself did not access self of the method (so self was
  not added to its parentfpstruct during the typecheckpass), then the
  unconditional reference to self when creating the call caused a compiler
  crash (introduced in r30908)

    it for the first time -> if fieldvarsym.llvmfieldnr got loaded by
    the compiler before evaluating the llvmst expression and if the
    llvmst hadn't been built yet, this llvmfieldnr was not yet initialized

cf2e46c2c1 * reworked external symbol handling on llvm to deal with the fact that 
a single external symbol may be used with multiple declarations that
    have different types:
   o always declare an alias with the Pascal-mangled name that aliases the
     external symbol, with the type of that Pascal declaration
   o if the external symbol is not actually external but in the same unit,
     we will determine the type of that symbol via its declaration and
     insert type conversions in the alias declarations in case they use a
     different type
   o if it is external (so there is no declaration from which we can determine
     its real type) and there are nevertheless multiple aliases for it with
     different types, we just take the type of the first alias and insert
     type conversions for the other aliases. LLVM will take care of the
     conflicting types in multiple modules when performing WPO if necessary

* handle function result of FPC_MUL_WORD correctly
  * use mov ...,r1 to load a register with zero instead of clr ..., this might enable the register allocator to 
    coalesce these moves in the feature
  * use tst/dec instead of cpi/sub in the shifting loops, this reduces register pressure on r16 and higher
