llvm-6502/include/llvm/Support/Dwarf.h
Frederic Riss 54d6b1b71e Modernize doxygen comments in Support/Dwarf.h 
In post-commit review of r219442, Rafael pointed out that the comment style
of the newly introduced helper didn't follow LLVM's coding standard.
Modernize the whole file to the new standards.
