[yaml2obj] Remove --format option in favor of YAML tags Summary: Our YAML library's handling of tags isn't perfect, but it is good enough to get rid of the need for the --format argument to yaml2obj. This patch does exactly that. Instead of requiring --format, it infers the format based on the tags found in the object file. The supported tags are: !ELF !COFF !mach-o !fat-mach-o I have a corresponding patch that is quite large that fixes up all the in-tree test cases.

# RUN: yaml2obj %s | obj2yaml | FileCheck %s
[obj2yaml][yaml2obj] Support for MachO bind opcodes This adds support for YAML round tripping dyld info bind opcodes. Bind opcodes can have signed or unsigned LEB128 data, and they can have symbols associated with them. llvm-svn: 270901
