Teresa Johnson 9937f43a8d [ThinLTO] Pass down opt level to LTO backend and handle -O0 LTO in new PM ... Summary: The opt level was not being passed down to the ThinLTO backend when invoked via clang (for distributed ThinLTO). This exposed an issue where the new PM was asserting if the Thin or regular LTO backend pipelines were invoked with -O0 (not a new issue, could be provoked by invoking in-process *LTO backends via linker using new PM and -O0). Fix this similar to the old PM where -O0 only does the necessary lowering of type metadata (WPD and LowerTypeTest passes) and then quits, rather than asserting.
