Duncan Sands b847bf547b 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.

Rafael Espindola 44bbe36de6 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.

Rafael Espindola dee3062373 Revert previous two patches while I try to find out how to make both 
linux and darwin assemblers happy :-(

Rafael Espindola 34a06a0802 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.

Rafael Espindola bbc0ac2236 Revert previous patch. Some targets don't support uleb and say 
they do :-(

Eli Friedman 7e2f4ce439 Until uleb/sleb are MC-ized, add a hack to make them work with ELF object 
emission.
