qfloat16: suppress warning caused by Clang macro we used
Clang implements the _cvtss_sh intrinsic by way of a macro, which
uses a C99 extension and that's not allowed in C++ mode:
float16.h:119:11: error: compound literals are a C99-specific feature [-Werror,-Wc99-extensions]
/usr/bin/../lib64/clang/3.9.1/include/f16cintrin.h:76:55: note: expanded from macro '_cvtss_sh'
Reported at https://bugs.llvm.org/show_bug.cgi?id=32491.
