} else if (D.getLTOMode() == LTOK_Thin)

lgrey: Do you think this should interact with
134275d994d5fb38edfeb587ba45c8f495c8bf66 in any way, or should have any other
interesting side effects?
From what I understand, it tells the linker to put temporary files created for
LTO in the given directory, but then the clang driver cleans up that directory
when it exits (potentially after running dsymutil). But most people run
dsymutil later, separately, so I think there should be no interactions there.
