Hey Evgeniy,
This is failing on Darwin:
http://green.lab.llvm.org/green/job/clang-stage1-configure-RA_check/30480/consoleFull#-121919748349ba4694-19c4-4d7e-bec5-911270d8a58c
This is exposing what I think is an existing bug: it looks like
-fsanitize=cfi and -flto=thin combined somehow cause clang to emit raw
bitcode (instead of mach-o wrapped bitcode that ld64 expects)
I filed PR32741 and tried to disable the darwin * thinlto tests in r301065.
