Added an option (-i) to have dump_syms output header information only.
It is often helpful to check if a particular symbol file dumped by dump_syms actually matches a version of a binary file we have. The symbol output contains an ID which can be used to see if it matches the binary file. Unfortunately, this ID is internally calculated and not a standard hash of the binary file. Being able to output the header information only will allow users to determine whether their symbol file is up to date or not. R=jochen@chromium.org BUG=561447 Review URL: https://codereview.chromium.org/1864823002 . Patch from David Yen <dyen@chromium.org>.
