Adds a readobj dumper for 32-bit and 64-bit section header tables, and extend support for the file-header dumping to include 64-bit object files. Also refactors the binary file parsing to be done in a helper function in an attempt to cleanup error handeling. Differential Revision: https://reviews.llvm.org/D63843 llvm-svn: 365524
