* partially converted the threadvar handling in tcgloadnode.pass_generate_code
  to use the hlcg in order to support the i8086 far data memory models. Only the
  instructions that handle the case when there's no thread manager installed
  (FPC_THREADVAR_RELOCATE=nil) are converted, since that's what's used on the
  msdos target. The rest still uses the low level code generator.
