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

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

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")

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

c9f8703679 + set ref.segment to NR_SS for all temps/localvars on i8086. This allows the 
segment to survive e.g. several nested vecnodes, which cause the base register
  to change from BP to something else. In the cases where the ss: prefix is not
  needed, it is removed by make_simple_ref.
+ remove the ss: prefix in the several cases where make_simple_ref isn't called
  (namely spilling and tcg8086.a_call_reg_far)

1df3039424 + LLVM temp allocator based on new R_TEMPREGISTER register class. For every 
temp we allocate, we set the base register to a newly allocated
    R_TEMPREGISTER. This allows for uniquely identifying a temp even if its
    offset is modified.

5af873ee5b * x86 targets: Profiling shows that quite a bit of time is spent in findreg_by_number(), despite it uses binary search. Worse, it is repeated for every piece of register information. Trying to get rid of some of these calls: rearranged registers so that their "opcode" matches 3 LSBs of superregister number (with a few exceptions described at the beginning of x86reg.dat). This allows to lookup opcodes in regval() with O(1) complexity, and removes need in rXXXop.inc files.
