c25c908977 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.

2d28617de2 Move getInitialFrameState from TargetFrameInfo to MCAsmInfo (suggestions for 
better location welcome).

ba9934648f 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.

0bbe0b440e 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.
