The parser provides a convenient interface for reading llvm stackmap v1 sections in object files. This patch also includes a new option for llvm-readobj, '-stackmap', which uses the parser to pretty-print stackmap sections for debugging/testing purposes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@240860 91177308-0d34-0410-b5e6-96231b3b80d8
