0da38dbc79 + implemented support for the 'dgroup' (addr_dgroup) relocation type in the omf 
internal object writer

778a678956 * use a 4 byte alignment for the dwarf debug sections on i8086 (not sure if 
that's correct for 16-bit dwarf, but currently the compiler emits 4-byte
  tai_aligns, so setting the section alignment to 4 avoids problems in the
  internal object writer)

5a1ce6162b * set the bss, rodata and rodata_norel section alignment to 2 bytes for the i8086-msdos target

5c8965fea5 * in the inline asm reader, treat [var] reference as "word" instead of "dword" 
when "var" is of dword size. This fixes spurious generation of a $66 prefix
  and makes the code consistent with what Tx86Operand.SetSize does (and what is
  then used for checking the operand sizes of all operands of the instruction in
  Tx86Instruction.CheckOperandSizes).

c3515f743f * generate 16-bit (instead of 32-bit) instructions for push/pop of a segment 
register in an inline asm block on i8086

3be51e1455 * fixed endless recursion in tabstractrecorddef.contains_float_field() in 
case a record contains an internal typed constant of its own type
    (which happened becuase such a typed constant is also fieldvarsym, solved
     by checking for sp_static) (mantis #27880)
  * fixed several other similar cases in the compiler where we are only
    interested in instance fields, but processed all fieldvarsyms

25a834087e + choose the correct version of "Jcc near" to use on i8086 (386+ or 8086+) 
depending on the specified target cpu type
+ support the \60..\62 magic codes on i8086 in the internal asm writer

2cf6852910 + added i8086 instruction entries for Jcc near (which is actually a 386+ 
instruction), that encode it as two i8086 compatible instructions:
    JNcc short +3
    JMP near target

bfd5670cc8 + support new magic code \23 in the internal asm writer - same as \13, but with 
the condition inverted; this will be used to simulate near conditional jumps
  on processors earlier than 386 (i.e. "Jcc near target" will be encoded as
  "JNcc short +3; JMP target")

9079227c56 * don't give an internalerror when trying to prefetch a regvar or even 
something without a location at all; it's a hint/optional operation,
    so if there's nothing to prefetch just don't do anything
    (mantis #27811)

6a7fff644a * align non-code sections with zeros, instead of nops in the nasm asm output 
writer, so they match the behaviour of the internal object writer (so it
  becomes easier to compare to the binary output of the omf object writer)

d6de2c03cb * generic part of r26050 from the hlcgllvm branch: made tcgvecnode hlcg-safe 
o in particular, add tdef size information to the update_reference*()
     methods, and factored out offset adjustments into its own method
   o also make sure the passed size to update_reference*() corresponds to the
     actual size of the index, as it's no longer guaranteed to be ptruint
     since the previous commit

5946328ed6 * CPUs not having CMOV apparently do not support the newly introduced Multibyte NOPs (Agner, Optimizing subroutines in assembly 
language, An optimization guide for x86 platforms, Page 87), so restored the 32 Bit part of the old alignment 
  bytes for use on those old CPUs and use it depending on the CPU switches

2d3ab816b0 * Tcgx86.g_concatcopy use: copy_move (mov sequence) instead of copy_string (rep 
movsb) when copying a 4 byte block on i8086, when optimizing for size. 4 movs
  are usually shorter than the instructions needed to setup rep movsb and also
  greatly reduce register pressure. This fixes i8086 snapshot building with -Os,

d24382e8f8 * x86 AT&T writer: never ever drop "@GOTPCREL" relocation, because it results in corrupted code (at least, "mov foo@GOTPCREL(%rip),%reg" must change to "lea foo(%rip),%reg" to remain equivalent, but this must be handled elsewhere anyway. Assembler writer should just write generated code as is).
