b17087a645 - removed debug writelns after r30800 
git-svn-id: trunk@30802 -

f1252d7582 - removed unnecessary setting of TargetMethod and TargetDatum (since these are 
always set in the following 'if' statement) in TOmfRelocation.BuildOmfFixup

7923b6142e + finished the internal omf library writer (implementing writing of the library 
dictionary at the and of the file) and enabled it for the i8086 internal asm

a365da0b44 + added class (empty for now) TOmfLibObjectWriter and hook it as an internal ar 
in the omf internal assembler constructor. Note it is not used yet, because of
  the af_needar assembler flag.

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)

7fca6dd6c1 * set the properties of the dwarf debug info sections in the omf obj writer 
as required by wlink in order to be recognized and handled as debug info
  (i.e. class=DWARF, use32)

c407f61107 * generate the omf alignment based on the value of SecAlign, instead of 
duplicating the code from sectiontype2align in the TOmfObjSection constructor

a7e059c875 + support segment relocations in the omf writer

nickysn
03e8c3ae05 + support RELOC_RELATIVE relocations in the omf object writer, by using omf's 
"self relative" (instead of "segment relative") fixups. "Hello world" and
  fpctris in the small memory model now work (under dosbox, at least) with the
  internal object writer.

35e008e44b * TOmfRelocation modified to build the omf FIXUP subrecord later, during 
writeData, when the ObjSection indexes are available; now we fill the proper
  section/segment indexes, instead of hardcoded values.
