Since users typically don't really care about the .dwo / non.dwo distinction, this patch makes it so dwarfdump --debug-<info,...> dumps .debug_info and (if available) also .debug_info.dwo. This simplifies the command line interface (I've removed all dwo-specific dump options) and makes the tool friendlier to use. Differential Revision: https://reviews.llvm.org/D37771 llvm-svn: 313207
