This patch adds a new flag: `--preserve-input-debuginfo-format` This flag instructs the tool to not convert the debug info format (intrinsics/records) of input IR, but to instead determine the format of the input IR and overwrite the other format-determining flags so that we process and output the file in the same format that we received it in. This flag is turned off by llvm-link, llvm-lto, and llvm-lto2, and should be turned off by any other tool that expects to parse multiple IR modules and have their debug info formats match. The motivation for this flag is to allow tools to not convert the debug info format - verify-uselistorder and llvm-reduce, and any downstream tools that seek to test or mutate IR as-is, without applying extraneous modifications to the input. This is a necessary step to using debug records by default in all (other) LLVM tools.
