This makes llvm-pdbdump available on all platforms, although it will currently fail to create a dumper if there is no PDB reader implementation for the current platform. It implements dumping of compilands and children, which is less information than was previously available, but it has to be rewritten from scratch using the new set of interfaces, so the rest of the functionality will be added back in subsequent commits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@228755 91177308-0d34-0410-b5e6-96231b3b80d8
