DWARF standard claims that each compilation/type unit header in .debug_info/.debug_types section must be followed by corresponding compile/type unit DIE, possibly with its children. Two situations are possible: * compile/type unit DIE is missing because DWARF producer failed to emit it. * DWARF parser failed to parse unit DIE correctly, for instance if it contains some unsupported attributes (see r237721, for instance). In either of these cases, the library, and the tools that use it (llvm-dwarfdump, llvm-symbolizer) should not crash. Insert appropriate checks to protect against this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@237733 91177308-0d34-0410-b5e6-96231b3b80d8
