db5e67c3fe + introduced a new type TRelocDataInt for use as the 'data' parameter for 
TObjData.writeReloc; on i8086 it was changed to longint to allow using 32-bit
  relocations
+ added support for writing 32-bit OMF relocations

4f8baf29c6 + handle RELOC_FARPTR48 relocations as well in TOmfObjData.writeReloc; this is 
not used yet, but is added for completeness (and might be useful, if we add an
  i386 target, that uses the OMF object format)

c8e20dfe74 + added i8086-specific consts RELOC_ABSOLUTE16 and RELOC_RELATIVE16, which are 
aliases for RELOC_ABSOLUTE and RELOC_RELATIVE
* use RELOC_ABSOLUTE16 and RELOC_RELATIVE16, instead of RELOC_ABSOLUTE and
  RELOC_RELATIVE in the linker-related parts of the OMF support (OMF object
  reader and MZ exe output). This will make the code more readable, when 32-bit
  relocation support is added to the linker. It will also make easier to reuse
  this code for i386, in case we add an i386 target, that uses the OMF object
  format.

bbe8e346e0 * handle tc_equal typeconversions from conststring to a stringdef in 
simplify, so that shortstring -> shortstring constant string conversions
    are simplified for LLVM too (it leaves regular tc_equal type conversions
    because often the type is still somewhat different), which is required
    for the code in tasmlisttypedconstbuilder.tc_emit_stringdef() (it
    assumes the result of inserting a type conversion is again a
    stringconstant if it can be handled at compile time)

49a83b2872 * allow targets to keep certain type conversions for equal types in 
inserttypeconv()
   o keep typeconversions between structurally equivalent but semantically
     different procvardefs for LLVM and JVM, because they're different
     types there

e877bae4fc + add 'jmp rm16' and 'call rm16' before the rm32 versions on i8086, so the 
16-bit version is picked up by default for opsize=S_NO. Previously the 386
  version was picked on i8086, but the generated code was correct, because we
  don't yet generate a 0x66 prefix for "\325", which leads to many 32-bit
  instructions not being assembled correctly with the internal asm obj writer on
  the i8086

a508f9e5d3 + added check if the selected cpu is 386+ when writing a 66h or 67h prefix in 
the i8086 internal object writer. This allows weeding out spurious 386
  instructions, as is similarly done by NASM when using it as an external
  assembler.
