fa3b0ca312 * support marking defs created via the getreusable*() class methods as 
"don't free even if not registered"; use for defs that may not be written
    to a ppu file, but that must nevertheless survive the compilation of the
    current module
  * mark all defs created for para locations as "don't free even if not
    registered", because we don't discard and recalculate all para locations
    after a module has been compiled (since that's not needed)
   o solves issues if the paralocations for a routine in the interface of
     unit A are calculated while the implementation of unit B gets
     compiled, and a new reusable type is allocated at that point which
     is not used anywhere else (after r32160)

862348c317 * Keep the GOT offset in a virtual register for i386 non-darwin platforms. 
It fixes PIC code generation with GOT for i386 with enabled optimizations. Bugs #28667, #28668. 
  Prior the fix I have not been able to compile even RTL with -O2 due to not enough free registers, since EBX is reserved for GOT.

  It can be further optimized to teach register allocator to not spill the GOT register if possible.

0fc1fd6ac1 * replaced current_procinfo.currtrue/falselabel with storing the true/false 
labels of LOC_JUMP in the node's location. This generates some extra jumps
    for short circuit boolean and/or-expressions if optimizations are off, but
    with optimisations enabled the generated code is the same (except for JVM
    because the jump threading optimisation isn't enabled there yet).

3d9713b9c8 * has_single_field() now looks recursively into fields that are aggregate 
types until it finds a non-aggregate type, and then returns "true" if
    that aggregate (record or array) contains one element
  * it now also returns the type of that element directly rather than a
    tfieldvarsym, since we only care about the type and in case of an array
    there is no field
