Adds support for the following flags: * --thinlto-index-only, --thinlto-index-only= * --thinlto-emit-imports-files * --thinlto-emit-index-files * --thinlto-object-suffix-replace= * --thinlto-prefix-replace= See https://blog.llvm.org/2016/06/thinlto-scalable-and-incremental-lto.html for some words on --thinlto-index-only. I don't really need the other flags, but they were in the vicinity and _someone_ might need them, so I figured I'd add them too. `-object_path_lto` now sets `c.AlwaysEmitRegularLTOObj` as in the other ports, which means it can now only point to a filename for non-thin LTO. I think that was the intent of D129705 anyways, so update test/MachO/lto-object-path.ll to use a non-thin bitcode file for that test. Differential Revision: https://reviews.llvm.org/D138451
