This refactors LTO compile to look more like COFF, where cache hits and misses are all funneled through the same code path.

Previously, cache hits were *not* being saved to `-object_path_lto`, which led to them sometimes falling out of the cache before `dsymutil` could process them. As a side effect of the refactor, cached objects are now saved with `-save-temps` as well, which seems desirable.

(Deleted `lld/test/MachO/lto-cache-dsymutil.ll` and rolled it into `lld/test/MachO/lto-object-path.ll`, since the cache-only, non object path approach is unreliable anyway).
