This introduces a new library to LLVM: libDebugInfo. It will provide debug information parsing to LLVM. Much of the design and some of the code is taken from the LLDB project. It also contains an llvm-dwarfdump tool that can dump the abbrevs and DIEs from an object file. It can be used to write tests for DWARF input and output easily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139627 91177308-0d34-0410-b5e6-96231b3b80d8
