  Log Message:
  -----------
  [llvm-objdump] Display locations of variables alongside disassembly

This adds the --debug-vars option to llvm-objdump, which prints
locations (registers/memory) of source-level variables alongside the
disassembly based on DWARF info. A vertical line is printed for each
live-range, with a label at the top giving the variable name and
location, and the position and length of the line indicating the program
counter range in which it is valid.

Currently, this only works for object files, not executables or shared
libraries.
