937b1e92a9 Add llvm::Metadata to manage metadata used in a context. 
This interface will be used to attach metadata with an instruction.

5f4ac848d9 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.

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!)

not hideous.  Also, fix some MSVC compile errors.
