When using `-fcs-generate-profile` with distributed thin-lto in the same
fashion we do for local thin-lto, we hit the following assertion:
6041c745f3/llvm/lib/Support/PGOOptions.cpp (L36)
Using local thin-lto with LLD for MachO, we set the missing path
automatically to a default value: https://reviews.llvm.org/D151589. In
this fix we add the same behavior.

;; Validate that we set up the ThinLTO post link pipeline at O2 and O3

;; Since LLVM tests already more thoroughly test this pipeline, and to

|
;; avoid making this clang test too sensitive to LLVM pipeline changes,
|
|
;; here we simply confirm that an LTO backend-specific pass is getting
