b258ff7cee Disable MDNode uniquing.
- Hopefully this unbreaks some llvm-gcc bootstraps.

40a0a72be8 While replacing an MDNode elment, properly update MDNode's operand list.
MDNode's operand list does not include all elements.

27616c3c80 Now Bitcode reader bug is fixed. Reapply 80839.
Use CallbackVH, instead of WeakVH, to hold MDNode elements.
Use FoldingSetNode to unique MDNodes in a context.
Use CallbackVH hooks to update context's MDNodeSet appropriately.

2d78fddeb4 For now disable MDNode uniquing. This fixes llvm-gcc bootstrap failure on certain Mac OS X 10.5. I am working on a proper fix.

7d42bfab6c 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!)
