83badeb894 Replace some instances of UniqueVector with SetVector, which is slightly cheaper. 
No functionality change.

b67c16fe92 Have the DbgVariable "isArtificial" and "isObjectPointer" not 
care about it being an argument variable so that we can decide
that captured block and lambda vars that don't happen to
be arguments could be an argument pointer.

Add the object pointer for one case onto the subprogram die.

853a000638 Recommit, with fixes: 
Add some support for dealing with an object pointer on arguments.

    Part of rdar://9797999

which now supports adding the object pointer attribute to the
subprogram as it should.

e2dae503e6 Revert "Add some support for dealing with an object pointer on arguments." 
This should be done on the subprogram, not the variable itself.

dde7784606 Temporarily revert c23b933d5f8be9b51a1d22e717c0311f65f87dcd. It's causing 
failures in the debug testsuite and possibly PR13486.

e8949ecfa6 Move lib/Analysis/DebugInfo.cpp to lib/VMCore/DebugInfo.cpp and 
include/llvm/Analysis/DebugInfo.h to include/llvm/DebugInfo.h.

The reasoning is because the DebugInfo module is simply an interface to the
debug info MDNodes and has nothing to do with analysis.

c551c1c5f9 Add support for a new extension to the .file directive: 
.file filenumber "directory" "filename"

This removes one join+split of the directory+filename in MC internals. Because
bitcode files have independent fields for directory and filenames in debug info,
this patch may change the .o files written by existing .bc files.

630d8ce36b Until now all debug info MDNodes referred to a root MDNode, a compile unit. This simplified handling of these needs in dwarf writer. However, one side effect of this is that during link time optimization all these MDNodes are _not_ uniqued. In other words there will be N number of MDNodes describing "int", "char" and all other types, which would suddenly grow when each object file starts using libraries like STL. 
MDNodes graph structure such that compiler unit keeps track of important MDNodes and update dwarf writer to process mdnodes top-down instead of bottom up.
