Start using the AttributesImpl object to hold the value of the attributes. All
queries go through the interfaces now.
This has one unfortunate consequence. I needed to move the AttributesImpl.h file
into include/llvm. But this is only temporary! Otherwise, the changes needed to
support this would be too large.

This opaque class will contain all of the attributes. All attribute queries will
go through this object. This object will also be uniqued in the LLVMContext.
Currently not used, so no implementation change.
