2e30b92c79 * removed the 'near ignored' and 'far ignored' inline asm warning messages on 
the i8086, as 'near' and 'far' actually work there. Some forms may even work
  on the i386, but that's not tested very well for now, so we leave the messages
  there on i386 and x86_64.

ed211b9888 * don't use symid anymore as fallback when sorting fields, as it's no longer 
guaranteed to be set. Instead, temporarily assign fieldoffsets to determine
    their order in the sort function (fixes webtbs/tw15415 with -O4 after
    r32153)

2cea723a0d * only write the parts of the unit localsymtables that are actually needed: 
the defs and syms (recursively) referred by inline routines and by the WPO
    info
   o defs and syms are no longer added immediately to the module's deflist/
     symlist, even if they are created as "registered". Instead,
     "doregister=true" simply means "add it to the symbol table at the
     top of the symtable stack"
   o normally only when a sym/def is deref'ed, it gets added to the module
     symlist/deflist and defid/symid gets a (unique) value
   o in cases where we use(d) the defid to construct unique names within the
     current module, you now have to call call the tdef.new unique_id_str()
     method. If the def was not yet registered, we will reserve room for it
     in the deflist (to get a unique id), but the defid gets set to a
     negative value computed from its position in the deflist. Should it
     have to be written to the ppu file later on, the defid will be
     modified to the actual position in the deflist. For both values,
     new unique_id_str() will return the same result so that references
     to this def before and after actual registrations are the same (needed
     for the JVM backend, but also a good principle in general)

   Overall: don't directly use symid/defid anymore to get unique identifiers,
     but use tdef.new unique_id_str() instead (if necessary, a similar routine
     for tsym can be added)

   The result is the ppu file size gets reduced significantly after its big
   increase as a result of the high level typed constant builder (which creates
   a lot of defs). The result is even more efficient than before, as other
   unneeded defs/syms from the localsymtables don't get saved/restored anymore
   either.

5771073e0b * Fixed general peephole optimization of conditional jumps after r30446. It has been broken, since r30446 had added some IsJumpToLabel() checks, which tests for unconditional jump, but the optimization code expects also conditional jumps. 
- Renamed IsJumpToLabel() to IsJumpToLabelUncond() to avoid confusions.
  - Added IsJumpToLabel() to check for any jump to a label.
  - Added comments.

7fc3ed2644 Fix a broken OpCp2Op optimization. It needed the added NR_DEFAULTFLAGS allocation to not break subsequent optimizations.
