afa5a34b30 Do not use StringRef in DebugInfo interface. 
This allows StringRef to skip controversial if(str) check in constructor.
Buildbots, wait for corresponding clang and llvm-gcc FE check-ins!

b5df28a151 Incorporate various suggestions Chris gave during metadata review. 
- i < getNumElements()  instead of getNumElements() > i
- Make setParent() private
- Fix use of resizeOperands
- Reset HasMetadata bit after removing all metadata attached to an instruction
- Efficient use of iterators

740d0db812 Copy metadata when value is RAUW'd. It is debatable whether this is the right approach for custom metadata data in general. However, right now the only custom data user, "dbg", expects this behavior while FE is constructing llvm IR with debug info.

2a610c7387 Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well. 
This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!)
