[lld-macho] Implement -dependency_info (partially - more opcodes needed) Bug: https://bugs.llvm.org/show_bug.cgi?id=49278 The flag is not well documented, so this implementation is based on observed behaviour. When specified, `-dependency_info <path>` produced a text file containing information pertaining to the current linkage, such as input files, output file, linker version, etc. This file's layout is also not documented, but it seems to be a series of null ('\0') terminated strings in the form `<op code><path>` `<op code>` could be: `0x00` : linker version `0x10` : input `0x11` : files not found(??) `0x40` : output `<path>` : is the file path, except for the linker-version case. (??) This part is a bit unclear. I think it means all the files the linker attempted to look at, but could not find.
