[PATCH] Add -bare option to llvm-objdump

[Steve King]

The -bare option keeps objdump output consistent with test expectations regardless of host platform.  As discussed on the list, default llvm-objdump output could change per host:  GNU style for Linux, otools for Apple, etc.  Diagnostic tests cannot depend on the per-host default.  Tests only need updating (a tedious process) if -bare output changes.

If this is agreeable, I'd like to keep the -bare option and -d consistency patches unified since both touch the same line in large number of diagnostic test files.
