I think this change introduced the following warnings, where `auto &` is used
for types that are always copied. It would be great if you could take a look.
lvm-project/clang/lib/CodeGen/CGOpenMPRuntime.cpp:8011:24: warning: loop
variable 'L' is always a copy because the range of type

does not return a reference [-Wrange-loop-analysis]
