1e33924f73 + support procvardefs (address only) in i8086's hlcgcpu.getaddressregister; this 
fixes e.g. obtaining the address of a method in i8086 far code memory models
  after r32414

ad92f4e80a + implemented thlcgcpu.a_op_const_reg with far pointer support for i8086, so 
that second_class_to_intf can be converted to the high level code generator

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)

09218c88aa + optimizations in tcg8086.g_flags2reg for the case where the carry flag or the

actually export them from the .exe or .dll, but they can now be used as

bdfd23cc2e + new target switch "FarProcsPushOddBP", which causes the i8086 compiler to push 
odd values of BP if the procedure is far. Enabled this by default for Win16.

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).
