Eric Christopher c1c8a1bb6a 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.

Eric Christopher e341776c1e 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.

Eric Christopher c44e973a36 Revert "Add some support for dealing with an object pointer on arguments."
This should be done on the subprogram, not the variable itself.

Bill Wendling e38859dc8e 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.

Nick Lewycky 40f8f2ff24 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.

Devang Patel eb1bb4e419 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.
