The change to the above named file breaks building any C++ code
containing _Float16 with devel/llvm80-8.0.0.r2 (and probably later, but
not 8.0.0.r1 or any earlier LLVM) on head (but not
projects/clang800-import, obviously). Example error, from our own copy
of LLVM libunwind:

--- libunwind.o ---

*** [libunwind.o] Error code 1

Upstream LLVM has already reverted this:

world builds successfully after applying the upstream revert. Ports that
use the clang portion of devel/llvm80 when set in DEFAULT_VERSIONS, ie
gecko@, also build successfully.
