objtool: Add ORC unwind table generation Now that objtool knows the states of all registers on the stack for each instruction, it's straightforward to generate debuginfo for an unwinder to use. Instead of generating DWARF, generate a new format called ORC, which is more suitable for an in-kernel unwinder. See Documentation/x86/orc-unwinder.txt for a more detailed description of this new debuginfo format and why it's preferable to DWARF.

objtool: Move synced files to their original relative locations This will enable more straightforward comparisons, and it also makes the files 100% identical.
