549d0683b1 Add back the MC bits of 126425. Original patch by Nathan Jeffords. I added the 
asm parsing and testcase.

4c8932e3b8 Add an option to pad an uleb128 to MCObjectWriter and remove the uleb128 encoding from the DWARF asm printer. 
As a side effect we now print dwarf ulebs with .ascii directives.

better location welcome).

0514e10276 Speculatively revert commit 127478 (jsjodin) in an attempt to fix the 
llvm-gcc-i386-linux-selfhost and llvm-x86_64-linux-checks buildbots.
The original log entry:
Remove optimization emitting a reference insted of label difference, since
it can create more relocations. Removed isBaseAddressKnownZero method,
because it is no longer used.

3e954d16f4 Second try at making direct object emission produce the same results 
as llc + llvm-mc. This time ELF is not changed and I tested that llvm-gcc
bootstrap on darwin10 using darwin9's assembler and linker.

3dc2b4cba7 Add an EmitAbsValue helper method and use it in cases where we want to be sure 
that no relocations are used (on MochO).
Fixes llc producing different output from llc + llvm-mc.
